Thanks for all your replies. Maybe I should say a little more about myself because I agree with adam_k that depression is caused by real reasons. I'm a 23 year old male and I have no friends. I haven't had a real friend since the first grade. I've never had any close relationships, period. I am extremely lonely all the time. Since kindergarten, I've gotten an overwhelming sense that I didn't fit in, and that I could never fit in. To this day I still feel like I don't belong anywhere, I'm unaccepted, an outcast, a failure, everything. I've gone to a lot of therapy and I know that I have a problem with negative thinking patterns (saying "never", "always", "should have", etc) but I can't seem to change it. I just can't see it any other way. I've had a lot of emotional trauma as a child because my dad was very unsociable; he never liked having guests/friends come over to the house, he constantly complained about everything, and I felt that he was disappointed in me. I was a late bloomer in everything, didn't learn to drive until I was 19, and my dad had this huge expectation of getting a job early and driving early like at age 15. I never got a job until after my dad died, and so I see myself as a failure in his eyes. When I was 20, I had to watch my dad die slowly and painfully in the hospital until finally we decided to pull the plug. He had diabetes to the most severity.

Back to now. I have taken a capsule of Vitamin D3 50k units over the course of 8 weeks, felt exactly the same afterward, am now on 2k unit supplement. I'm also taking a B-complex supplement.

I have a supportive family, but they all have no understanding of depression and they just don't "get" me so I feel very distant from them. I have no friends.

I've told my individual therapist my goals, and he says it wouldn't be wise to pursue them right now and he's right, I see no way of moving forward from here, I'm doomed.

I don't know if they checked my thyroid, no.

I have a good psychiatrist that prescribed the meds.

Genetic: Thanks for explaining Deplin, I had never heard of it before. I will definitely talk to my psychiatrist about it.

adam_k: I started on Prozac, but now I've been on Welbutrin for about 4 months and I can't tell any effect at the maximum dosage of 450 mg.
