I suffered with anxiety but for periods of my life, only weeks or a couple of months thankfully, my anxiety was debilitating. Like I couldn't get out of bed. I was prescribed an antidepressant but it made me feel so horrible and weird on the first day, I had to come off them. That first day I shat myself, stared at the wall for hours on end, and was just generally a zombie.
SO my experience was very brief and not positive, however I know that you generally need to be on them a few months to feel the effects, and obviously sometimes have to try different ones to see which works for you best.
So whilst my experience was bad, if I was in a bad enough place, I wouldn't say no to them again in the future if I was told it would help. I do think Dr's are too quick to throw them at you in some cases.
