Anxiety made my mind race all the time. I thought I had so many things wrong with me. I finally went to see a doctor. They did an EKG and upper body X Rays to rule out health problems and also sat and just talked to me. They told me I have some anxiety issues I need to seek help for. I now know that I have GAD from my Post Acute Withdraw Syndrome. It like comes in waves. I'll be fine for a few days and then feel bad for a few days. From my reading I've learned that it can last up to two years and gets easier as time goes on.
