My brother has had anxiety disorder since 1975 back when NO ONE even knew what a Panic Attack was. He had one after our father's funeral and had to go to the ER because he was sure he was having a heart attack at 22. The ER doctor sent him to a psych. doctor and from there he has been in treatment since, but he has always worked a full time job. He's on Lexopro now and several others. He likes to drink which makes it more of a problem, but he says that most men find they have no anxiety when they are drinking. Probably true but bad for his health.
I follow Roby Mitchell, M.D. www.drfitt.com
who graduated from Texas Tech med school and also has a PHD. He says most of the problem is thyroid and he does a lot of work with HORMONES since he feels that they control the body. He had advanced prostrate cancer and cured himself with diet and exercise. I found him when my son had Testicular Cancer. Check him out as he has a lot of vlogs on YouTube.
