Antidepressants sometimes stop working. I was on lexapro for 18 years and weened myself off over several months and feel so much better. The lexapro was making me more anxious, sensitive to noise, ringing in ears, numb with emotions and I wanted to stay home all the time. New research has shown that your gut flora plays a huge role in depression and can be alivated through diet & exercise. Look up Kelly brogan, md for more info. Good luck and just know I’ve been there. I couldn’t take my way through it because my issues were medically related.
