I dunno really. Lots of my cousins etc are pretty mental and one of them hears voices in his head etc so maybe its in the family. Before I went in I used to come home from work every evening and take 5-10 e's. I did that for about 6 months and for two weeks before I went in I didn't sleep at all so I suppose I just burned out
I had a full time job and was working there for 5 years but I lost it when I was admitted. Lost job, girlfriend,friends money etc but I got over it anyway.
