depression
"I got depression and anxiety after one summer of abusing ecstasy and acid.  This was 2003. 

For quite a while I didn't Medicate as I was still in denial. After about 2 years of suffering I started taking lexapro. It didn't do much. I began to get severe headaches. After 2 years I switched to Zoloft. Kept waiting for things to get better but they just got worse. I began to put on weight. To feel better I was binge eating junk food. I became sickly bloated, And had terrible OCD. Eventually out of desperation I switched doctors 2 yrs ago and he prescribed Wellbutrin xl. Thank god. The fog began to clear up, I felt optimistic, less anxious, lost weight. Am almost 80% better. Living a normal life. Welbutrin saved my life."
