I Am Desperate, I Went Off Of Sertraline... 150 Mgs.

I am desperate, I went off of sertraline... 150 mgs. cold turkey, 40 days ago. I did not know everything, I should have nothing but a living hell ! I thought it was bad before/ while I was on it know, but now, I feel like a vegetable/ walking Zombie ! Too much to explain all the classic symptoms. What's this going to cost me ? I can hardly think let alone type... I ddon't know if I can afford this ???
