Prescriptions.

I've been on celexa, lexapro, and then zoloft 200mg. And after awhile that wasn't enough. So my psychiatrist added on Wellbutrin. I only took it three days but the third day it messed me up so bad I couldn't drive, I started crying at a store cause I felt so weird and I couldn't remember anything. But I need something my depressions at a all time low. Any thoughts? I also took seroquel cause I have awful dreams from ptsd but he took that away cause I would sleep forever which I still do and gave me a blood pressure medicine to calm me down and put me to sleep but I just get light headed. What are some really strong and good antidepressants? I just dropped out of school. Got fired. Close to giving up.
