I was on Lexapro 5mg for GAD and for about 3 weeks until I had a panic attack and now my doctor moved me up to 10mg and it has been 1 1/2 weeks now and I have felt some difference, but I'm still having trouble with my thoughts. I am still thinking a lot about why I do the things I do, and depersonalization. Has anyone experienced the same things? I just feel hopeless and constantly worrying if Lexapro will work for me. Also how does Lexapro help with this? Sometimes I feel like this is all in my head and feel like I can't get rid of these thoughts.
