diagnosis?

I would like to know what you think I am suffering from, I'll describe the symptoms I have:
- I was always bad with people, I just never understood them. It's better now since I specifically trained myself in empathy.
- I've always been pretty unaware of my own emotions. At age 18 I remember thinking I had no emotions. Even now it's common to notice symptoms and then think "why is my heart beating so fast??".. although I've gotten a bit better at understanding what emotions I am feeling (I think)
- Everything is so hard. This is wrecking my life. Everything just scares me and stresses me out.. it's as if all my time is spent unsuccesfully trying to calm myself down. I don't know why but even doing simple thing like taking a shower, cooking food or going to the supermarket scare me a lot and are very stressful! There doesn't seem to be anything in particular that scares me, more generally "everything".
- I have plenty of friends (people seem to like me easily) but I don't see them often because I prefer to alone for the most part. It's just too stressful to be around people too often - as everything is too stressful.
- I can't complain about female interest (it's not uncommon to be approached by girls at social events even), but ultimately I'm always the one keeping things off. Not that I don't want to have a girlfriend, but the prospect is just too scary and stressful I think
- I don't have a sleeping rythm. I sleep some during the day, some during the night. Sometimes I sleep a lot, sometimes very little.
- There are some things I do compulsory, I think in an attempt to calm myself down. I smoke cigarettes almost constantly. I browse internet forums a lot. I don't know if I generally have a lot of pattern I keep repeating though
- If something peaks my interest, I will take it on fanatically. And I will usually get very good at it quickly too. (I once took a test and I have a high IQ) Stuff like chess, go (japanese board game).. or strategy games in general I get very good at. The last thing was poker, which I played on the internet. I made a good deal of money that way, but now I can't play anymore, the interest has faded and now it's just way too stressful (like everything else in life)
- I somehow managed to struggle myself into my last year of civil engineer (university study). Almost never gone to classes, and for the most part I took exams without having studied anything at all, or only a few hours before the exam. If there were tasks, I'd typically copy them from others.
- You probably can't tell I'm so panicy when you see me. In fact, people more often describe me as very calm and laid-back. My lack of activity probably looks more like laziness. (I have a very stoic expression and attitude I think)

Recently I've been taking some anti-depressants, like serlain (zoloft) and now anafranil (clomipramine) and lambripol, but it doesn't seem to help with my constant stress at all.

I'd really like to know what is wrong with me, and if there is something out that can help me. Are these symptoms I described typical of something?

Thanks a lot

sounds like some sorta depressive condition. possibly bi polar where it seems u have bursts of intense, fanatical interest in things. i would take as deep and honest a look at your self thats possible and try and see if theres anything problematic in your thinking, perceptions, values, beliefs and image of yourself. poke around and see whats happening deep within your mind. see if u really like yourself and if not why? challenge your thinking, mindsets, programs and beliefs. if it all seems clean and legit then i would look into different meds maybe. best wishes.
