How Much Do I Need To Take!!!

Yesterday I went to the doctor because I wasn't feeling any better. The doctor told me that I have a respiratory infection. She prescribed Allegra D and Amoxicilan. After that appointment, I had to visit the psychiatrist. I explained to her that the three pills a day of the Wellbutrin was affecting me so bad that I could not control my nerves. First she told me to take at least two pills and then work my way back up to three. I didn't want to do that because I was extremely scared of the side effects. So instead she wants to keep me on the Wellbutrin and she prescribed a new antidepressant called Cymbalta. So now I am on two antidepressants because she said I didn't look happy and that during the time I was taking the Wellbutrin, I should have experienced a better mood swing but I didn't didn't. I don't know what to do. I am scheduled to see her on January 18. I am seriously contemplating not going back after that. I don't want to take all of this medicine. After reading about all of the possible side effects, it just makes me nervous about all of it. There is a side of me that wants to take this stuff just for the sake of saying I tried and maybe that way, she will stop prescribing all of this stuff. I just want to feel normal again.
