I recently started Lexapro 16 days ago and it made me feel horribly flu like, and worsened my anxiety and depression to the point of not being able to function for several days. I was determined to tough it out. After about 11 days it started to improve. I woke up today feeling great! I feel more like myself than I have in years. It was a rough ride but certainly worth it. Hang in there! You are not alone.
