Coping with anxiety

Having a tough time at the moment coping with "everyday" things. I try to get out and forget about my troubles, but even if I feel better psychologically, my body always lets me down. E.G. thought I would try tai chi. Love it, but it aggravated my arthritic shoulders and compression fracture in my lower back. Also loved connecting with the ladies after class over coffee. Persevered, but the pain became too severe, so I had to quit. I have a skin disease called bullous pemphigoid, which is aggravated by stress and anxiety. That has flared up again because I am struggling. Most of the illnesses I have had throughout my life have been exacerbated or caused by my crazy, mixed up thoughts. I am 71 and thought by now I would have all my s--t together.
