Recently I had my first one night stand. It happened with a guy at a club and it happened very fast without us getting to know each other too much first. The problem is, the next day I felt extremely sad and depressed. I felt like I've been used and felt cheap. I was also sad that he didn't ask me for my phone number even though I wasn't interested in him. I felt unattractive and worthless. Is it normal to feel this way? Do guys ever feel this way too? How can I get over this post-one-night-stand depression?

I'm in desperate need of help! I have a great boyfriend but my ex-boyfriend and his new girlfriend constantly plague me. I literally stalk them, unable to let go. I have tried any means possible to learn about what is going on with their lives and I just want to move on. I'm a 21-year-old grad student right now and am on my break, so I have ample time to brood over this issue. Please help me get over this obsession!

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?
