What everyone above has said - antidepressants are not to be stopped abruptly. Weaning yourself off them is fine, so long as you've discussed this with a doctor, but going cold turkey will give you all sorts of Unpleasant side effects with a capital U. If you feel you're in a good place and want to stop taking them dial down the dose or frequency over a couple of weeks and pay attention to your mood and general sense of wellness.
I hope you feel better soon.
