Hi, Welcome to Healing Well.
No you will not fry your brain with antidepressants, but everyone has their own opinion about that. The fact of the matter is that once you have take an antidepressant for several years and stopped it then gone back on it and stopped again often times you will find that the medication isnt as effective the second/third time around & that sometimes it is more difficult for you when you go off it on those occations. The depressive symptoms come back sooner.
Look, you had to be taking the medication for a reason in the first place right? How about asking your doctor for something different? There are many good medications on the market that can help. You dont have to live your life feeling this way.
Take care and keep posting
