I have anxiety disorder and have tried many different prescriptions over the years, usually giving up because of extreme exhaustion and weight gain, only to go back to try new medications. The only one I found to have worked for me was Xanax however since my doctor doesn't want me to use it for every day, we are currently trying to find something else to work. I have tried Klonopin, Zoloft, Paxil and Buspirone. Now I am trying Lexapro. I am very worried since I have been reading on this site how Lexapro causes anxiety. I am trying to get rid of my panic attacks and anxiety not cause more. Not sure what to do. I'm desperate for help. I should mention that I am 55 and am post menopause.
