How do you deal with your fears? I have a fear of other people dying or of myself and others getting a disease. My imagination runs wild with these thoughts, and it's hard to control these worries. I'm always thinking "what if." My friends tell me not to worry unless it actually happens. I know this is true and good advice, but I find it hard to stop worrying. If you could give me some tips on how to control my imagination, it would be much appreciated.

1) I've recently just found out that my boyfriend of four years is bulimic... He hasn't told me, but I have put the puzzle pieces together after living with him for the past 18 months... I had even heard him purging in the bathroom while we were on vacation. I'm really struggling with this information and I don't know how to approach him about it... I'm guessing it has been going on for around six years now. How do I confront him about it??

2) I was wondering if bulimics lose weight rapidly, because I have a friend who I think may be bulimic, because she eats, but I think she may be throwing up her food. She has lost 25 pounds in the last month. She binges, and I would like to know how I can help her.

Is it possible to find female PSA, or other types of sexual fluids on another female? For example, if there was a case of women on women rape, could it be possible to find the woman's DNA on the victim? Like when they find semen on victims?

Whenever I am in a very stressful situation such as an approaching big deadline, my body gets unusually tired and sleepy regardless of how much rest I get. I sleep well but it never seems to be enough. Why do I get so sleepy and what can I do to prevent this change when stressful situations approach?

1) My boyfriend, who I have been dating for a while now, says that he is fat and I don't think he is. He is built, but he isn't fat. And he talks about it all the time, and I just don't know what to say to him. He said that when he used to talk with his other girlfriend about it, that she would say, "well, go on a diet," and he said that made him feel like he was fat. And I don't want to hurt his feelings, but I know that by losing weight, he would feel better about himself. But I like him for who he is and how he looks. But what should I say to him when he says things like he is fat, do you think I'm fat, etc.?

2) I am a male, 24 years old, height 5'10", and currently I weigh 143 lbs... When I was 17 or so, I weighed a hefty 190 lbs... at that time, that really had a negative effect on my self image, and now at 143, I still don't think I'm thin enough... I have lost all my weight 100 percent through diet and running about 20 miles/week... but I don't eat enough and I always worry before I leave home if I "look ok"? Do I have serious issues?!?

You have an excellent service and give great advice. That is why I feel comfortable asking you this question. About three weeks ago, a group of my friends and I went out to a movie and then a club where we each had some alcohol. After the club, we went back to a friend's room where the group gradually dispersed until there was only myself, two male friends, and one female friend. We began to play sex games. Eventually, we all were naked, on my friend's bed. The female of the group was the center of our activity. She seemed to want it and even encouraged what the three of us started doing to her.

Although we all were tipsy, it was a great sexual experience for all of us, or so I thought. My two male friends have no problem with what happened. The only thing is that my female friend won't speak to us or return any of our calls. I saw her walking down the street the other day and tried to talk to her, but she wouldn't even raise her head to look me in the eye. Do you have any idea what is wrong? Could my friend feel that she was raped? I want to apologize, but I'm not sure what to do.

When I get excited about going to see the boy I love or nervous about hanging out alone with him, I have to poop. Everytime. My stomach gets really upset and it cramps and then I have to poop. In most cases it's diarrhea and I never feel like I'm okay by the time I have to leave. Is there something I can do about it to limit it or just stop it in general? I love knowing that I get to see him but I hate the baggage I get beforehand.

Do you believe in going from one relationship that did not work to another, without regrets? How come some people can change their lives without looking back? Is it possible to grow old without regrets?
