I think my chronic anxiety was caused by drinking and drugs. I used to try to quiet the anxiety which then made it worse. I was also always worried about hiding my life and being pulled together enough to work and travel for work. Since I've stopped drinking/using I'm really surprised how much more calm I am. My blood pressure used to be through the roof at the doctor's office. I had an appointment a few weeks ago and it was almost normal. My doctor smiled and said "I think you're on the mend"
