Are you still skating as much as you were when you were on antidepressants? I mean if you are feeling like shit, low energy you won't be able to skate as much or at a higher level. I would also suggest not smoking weed if you have had psychosis before, you are already at high risk for it if you have experienced it once and weed can trigger it in those who are at risk, so a good idea to stay away. Also you sound like me with weed, I loved that shit, but I can't function when I'm smoking, I just become a typical stoner sitting around all day. If you are honest with yourself and know you don't have any symptoms of depression it should be fine to stay off, though you should talk to a Dr first. Just make sure you are honest with yourself and them, they will help you get off even if they don't think it's a good idea. I wouldn't take it if you don't have to, but if you do have depression escitalopram had pretty much no side effects for me and weaning off was easy. If you don't have serious side effects and have depressive symptoms you should see your dr for sure about if you should get on again. I'm comfortable with mental health and medication though. A few years ago remeron pretty much saved my life, and I eventually got off of it. That is the only antidepressant that I had withdrawals from and it was horrible. But I liked being on it. It was the first time I got good sleep in my life, I gained a lot of weight (was really skinny), no anxiety, outgoing, on top of shit, I also wasn't smoking though.
I've never had psychosis, just depression and anxiety. Comes and goes for me but I haven't been on antidepressants for a few years and I credit that to smoking much less/not at all. It kicked in when I smoked, and goes away when I quit.
