I'm 18 almost 19 and when I was 16 I lost my best friend (almost sister) to a bad crowd with drugs and stuff like that. Needless to say, I became very depressed and I was sent to a counciler. I was then sent to a psychiatrist where he prescribed me an anti-depressant, anti-anxiety, and a headache medication. I was diagnosed as clinically depressed and later diagnosed as bi-polar and went along with that explanation for about a year and a half. During this time I gained 30 pounds, became increasingly depressed, and neurotic (with cleaning and organization).
When I was 17 or so, I started bringing my friends in with me to my doctors appts. because I just wanted to show them that my doc was crazy, and he was. My mother didn't believe me so I quit my medication anyway for 3 months and went to my doctors appt. I brought my best friend at the time in to vouge for me. I told him I want to stop taking the medication, and he told me that he didn't recommend it because I would go threw withdrawals and I would become increasingly moody. My friend told him that I, perhaps, got even happier when I was off them. He told her that she wouldn't see side effects for at least three weeks, but I had been off for 3 months. I disproved his theory that I had bi-polar disorder, and then he proceeded to tell me that I have siezures. This guy was really messed up, and just wanted to keep me on medication and in his office, so he would make more money.
The moral of this long ass story is to never go to a psychiatrist, they will just tell you that you have problems that you don't really have. Take an over the counter drug, like Paxil, and talk to you closest friends, or people who are willing to listen. Don't get caught up in doctors and feel bad about yourself, it will only make it worse.
