From what ive read in this thread, i personally don't think your helping yourself by discussing your "problem." It sounds to me like your amplifying it. It also sounds like your life hasn't been exposed to much emotion. Your mom sounds like someone with little emotion. Your dad is male and thus spends more time thinking/eating food then thinking at all. Your friends may not be very emotional either. But alot of people are, and can be, very emotional beings. I know that my family is extremly emotional. Emotion is a well-liked trait, and i see no reason to block out what feelings you do have. Someone said that you being a female in your teenage is the sole cause of your problem. I tend to agree, however i think theres more to it then that, but going through adolescent IS increasing your emotional awareness.
What you need is distractions. Spending all day browsing/talking about your "problem" over the internet is not helping, at all. Neither is seeing a shrink or taking pills. I propose that to increase your well-being a good diet and strong excersise is key. Drink lots of water, eat lots of peanut butter (ie-good foods) and get involved more with sports. I play(ed) racquetball for five years now and the #1 rule to remember in the sport is "Don't beat yourself." I think this is what your doing and down the road your going to get worse if you keep thinking your mentally sick. You aren't mentally sick so stop stringing yourself over it.
