Help

I've been struggling to find a med that works for my GAD. It's been a year since I felt completely normal and happy. I was on Prozac with great success for about 5 years. When I tried to get back on it, I had a horrible reaction. I've tried Prozac, paxil, Lexapro none of which helped and gave me awful sided effects. My psychiatrist and I decided to do a genesight test. I tried pristiq only for one day because it made me feel so terrible. My anxiety and this whole process has caused me to become very depressed and feel hopeless. I feel like nothing is going to help and I'm just going to be stuck like this. I go to therapy. I have no known trigger, just a constant extremely nervous feeling. I've had blood work and my hormones checked. All normal.
