Re: how do you know????
While there may come a time when you are able to stop taking anti-depressants, feeling better on the meds does not mean you're cured. It means the meds are working! Some people will need the meds for the rest of their lives, and some may stop needing them when certain situations that may be causing the depression pass.
As for my own experience, I was on Wellbutrin a few years ago when I was in high school, but after I graduated I stopped taking it because my situation changed and I didn't need it anymore. I was fine for a couple of years, but just last fall I started a new school and got really depressed again. I'm on Effexor now for that and social anxiety, and although I do feel much better now, I know I'm not ready to stop taking it. I accept that it's something I may have to take for a while, maybe several years, but I do hope that some day I can stop. I think you just need to be aware of what's going on around you and ask yourself, if you stop the meds, is your depression likely to come back?
