DEAR ABBY: I am a 13-year-old who has already ruined her life. I stay up late, eat tons of junk food and yell at my sisters. It may not sound that bad, but on more than one occasion I have stayed up way past midnight.

I'm known as the one in the family who can drink a six-pack of soda at one sitting and eat can after can of tuna fish. My sisters are so worried about me, I've driven them to tears.

Every week I put on more weight. I've got acne and my teeth are horrible. Please help me, Abby. Nobody in my family understands what I'm going through. -- UNHAPPY WITH MYSELF IN SALT LAKE CITY

DEAR UNHAPPY: It sometimes takes a series of "baby steps" to change patterns that don't work for you. Self-improvement cannot be accomplished overnight, so please stop being so hard on yourself.

There is help for each of the problems you have described. The first step is to ask your parents to schedule an appointment for you with your pediatrician to discuss your nutrition and anger issues. Your doctor also can refer you to a dentist and a dermatologist. You would sleep better if you began a regular program of exercise.

P.S. A final thought: If your parents are unable to help, talk to a counselor at school when it resumes in the fall.

DEAR ABBY: I recently graduated from high school and will attend college in the fall. I will be rooming with my good friend, "Marla," whom I have known since second grade.

Marla's father has decided he won't buy her a computer (one of the school's admission requirements) or let her take her car to college. The reason? He expects me to allow Marla to use my computer when she needs it -- and to drive my car! Marla doesn't understand that this is unfair, and sees no problem with it.

Abby, I feel used, disrespected and hurt. I don't feel a friend would be so presumptuous. How can I set her straight? -- ANGRY IN ALABAMA

DEAR ANGRY: Have your parents call Marla's father and straighten him out regarding the computer and the car. Since the computer is an admission requirement, one must be provided for her. And as for your car -- no one should drive it who isn't listed as an "additional" driver on your insurance policy. Period.

P.S. Do not blame Marla. She is just trying to follow her father's "wishes."

DEAR ABBY: I am a 23-year-old woman in need of your advice. About five years ago I met and fell in love with a wonderful man. You could call us high school sweethearts. We dated for a year and nine months.

We broke up when he went into the Air Force, but I'm still very much in love with him. We e-mail each other almost every day, but I haven't been able to bring myself to tell him how I feel. Perhaps your advice could help me make the right decision. -- SECRETLY IN LOVE WITH A MILITARY MAN

DEAR SECRETLY IN LOVE: Some secret! He already knows you care for him since you are e-mailing him almost daily. And it's a safe bet that he has similar feelings. Tell him how much his communications mean to you and sign the next message "Love." After that, the next move is his.

DEAR ABBY: I am a 20-year-old college student. Last summer, I met "Irwin," a friend of my brother's. Irwin and I became good friends, and over time, I came to deeply respect and care for him. A few months ago, Irwin left to intern at a senator's office. He's finishing his senior year there.

As we were saying goodbye, he hugged and kissed me on the cheek, muttered something under his breath, then proceeded to kiss me gently on the lips. Irwin and I are both shy, and I don't know what to make of the kiss.

Could he possibly care for me, too? I don't know if kissing a friend on the lips is considered a "friendly gesture," or if it means something more romantic. I'm relying on your advice, Abby, so I'll know what to do when Irwin returns home. -- IT STARTED WITH A KISS IN KENTUCKY

DEAR IT STARTED WITH A KISS: It would be helpful if you could remember what Irwin muttered under his breath. When he comes marching home again, greet him with a kiss. Shyness can be overcome, and I think you've hooked a live one.

DEAR ABBY: I need your opinion. I'm 40, married 17 years, and have two young children. My husband has never been romantic -- no hugs, kisses, flowers or gifts. Once I asked him to just bring me a flower from our garden. Still nothing. He knows how much a little show of affection would mean to me. We've had many discussions about it, and I always end up in tears.

Well, I've met someone. He gives me hugs and small, thoughtful gifts, and he's willing to sit and talk to me for hours. This man makes me feel special, attractive and happy. I've had opportunities like this before, but I always held back because of my marriage. No more. I'm lonely and need to feel loved as much as I need air. Where do I go from here, Abby? -- CRAVING ATTENTION, NO CITY, NO STATE

DEAR CRAVING: You have a right to be happy, but having an affair is not the way to accomplish it. Stop the affair and offer your husband the option of counseling. If he refuses to go, go without him. Right now you are like a flower in the desert. Counseling will help you to decide rationally if you are better off with or without your spouse.

DEAR ABBY: I have been in a relationship with "Chuck" for eight years. We have lived together for seven.

Chuck and I haven't been physically intimate for more than five years. He long ago stopped saying those sweet "I love yous" every woman wants to hear.

I suspect that he doesn't love me anymore, and that he's having an affair with his ex-wife. I'm a good cook and I've always taken good care of him when he gets sick. I think that Chuck is living with me out of convenience.

What do you think I should do? Please don't tell me to leave him, because I haven't got the courage. -- STUCK AND UNHAPPY

DEAR STUCK AND UNHAPPY: Gather your courage, count to 10, and chuck Chuck. I guarantee that once you take the step, you'll experience enormous relief. I wouldn't wish anyone I cared about the life you are living now. You are a giver. You deserve to be happy and cherished, and you shouldn't settle for anything less.

DEAR ABBY: My husband and I were married several weeks ago in a beautiful, reverent, Christian ceremony. Our reception, held in an upscale restaurant, was designed to be both fun and tasteful. Everything from the dance music to the cake-cutting was planned to represent the love and respect we had for each other on our first day of wedded life.

That spirit was shattered by "Simone," my husband's brother's girlfriend. She took over our reception. Her shrill voice screamed at least 50 times for my husband and me to kiss and smear cake in each other's faces. She drank champagne straight from the bottle. She showed our guests X-rated photographs of her unmarried daughter's natural childbirth. She performed a "striptease" by whipping her skirt over her head and gyrating against other guests in a practically nonexistent thong. We didn't realize the extent of her misbehavior until we returned from our honeymoon and saw the video. The expression on the faces of our guests is horrified, and she dominates every scene.

Simone will no doubt be a permanent fixture in my husband's family. I do not want to cause a rift, but that vulgar woman ruined my wedding. I don't know how I'll control my feelings the next time Simone and I are thrown together. How would you handle this? -- MORTIFIED BRIDE IN NEW YORK

DEAR MORTIFIED BRIDE: I'd keep uppermost in mind that Simone may have a drinking problem that causes her lapses in judgment once she's had a few. I'd say this plainly to your new brother-in-law as I handed him a copy of the video. Sometimes a picture is worth a thousand words. And this is one of them.

DEAR ABBY: I am a 23-year-old single working woman, and I'm in love with an older married man in my office. This has gone on for about two years.

I have never acted on my feelings, and I never would. I wouldn't do anything to jeopardize his marriage and have never told him how I feel. However, a little incident recently made it pretty clear he feels the same way I do.

No, it's not what you're thinking. We simply shared a "moment" (corny as it sounds). It was like in the movies when the music soars, the man and woman suddenly lock eyes and slowly move in for "the kiss." In fact, that's exactly what happened -- but I pulled away.

I don't know why I hesitated. I have fantasized about that moment for the longest time. But when it finally happened, I couldn't go through with it.

Now when I see him, I ache inside. It's a different kind of pain than anything I've ever experienced. I desperately need your help. I'm not even sure what I'm asking. I'm afraid if I'm ever again in a position to kiss him, I might just do it, and I'm afraid of where it would lead. Any advice? -- ACHING AND ANXIOUS IN NEW JERSEY

DEAR ACHING AND ANXIOUS: You appear to be a sensible and honorable woman. You and I both know you and this man are swimming in dangerous waters. The wisest thing you can do is to remove yourself from any situation that could tempt you both and cause future pain, embarrassment or regret. If that means a change of employment, so be it.
