I've been on Lexapro for a few years now. I go through bouts of suicidal thoughts still but it really helps with my anxiety. For the most part it's helpful but there are a few times when I'll stop taking it for days at a time and feel horrible and realize I need it. This battle inside me is itself depressing. Good luck with your treatment, in the long run it really can be beneficial, I just have to want mine to be to get there.

As far as MJ goes it's also been very helpful curbing my suicidal thoughts. When I was smoking daily for a month I never had one but when I cut back to 1-2 times a week it came back. I smell a potential study.
