Any ideas on how to help nervousness or anxiety?

Yes: Psychiatrist consultation may help you rule out medical conditions as a cause, as well as diagnosing and treating it appropriately. Do not delay the process. Get better soon, and back to normal.

Dr Satulovsy - agree: Talk about feelings ; address problems. Don't avoid them. Aim for 7.5 - 8 hours of sleep/ night. Daily physical activity is optimal in a green space. Eat healthfully. Cut out junk carbs, caffeine ; alcohol (or moderate). Try qi gong, tai chi, acupuncture, acupressure, homeopathy, meditation, yoga, exercise program, deep breathing exercises or progressive muscle relaxation.
