Hello, I was diagnosed with GAD 10 years ago and have been on Lexapro during that time. I have been in therapy and managed life. Last year I was diagnosed with PTSD and was given Xanax and additional therapy, and returned to work. I am out of work with GAD, PTSD. I'm on Lexapro but klonopin was substituted for the Xanax. I am not getting any relief. I also have been trying to regulate my thyroid. I'm looking for a SSRI that doesn't cause hair loss and has minimal side effects. I do not think the Lexapro is working anymore.
