Suffer from obsessive compulsive anxiety and irrational thoughts. I know these are just fears and not things that are actually going to happen but it is crippling. I have been on lexapro 20mg for 10 weeks now and. 5mg of xanax as needed. I try not to take the xanax. It was getting better. I felt solid at about the 7week mark. I suffered the loss of a grandparent 2 weeks ago and the anxiety and thoughts and fears are back. I thought with the meds this wouldn't happen. Am I not on the right meds? Has this happened to anyone else?
