Damn we are very much alike Poly. I also have GAD. High anxiety moderate depression. I started taking Citalopram last October it was weird at first. Tired throughout the day and weird vivid dreams at night. Eventually I got used to it and my thoughts were less racing. Recently they added valbutrin (botched spelling) specifically for my depression and it has helped tremendously.
What I also suggest is getting exercise and definitely trying to go back to therapy weekly! It's been wonderful for me.
See I'm not always a troll
