Exercise aerobically for 30 minutes every morning.
Yes, it sounds simple and even ineffective - but it works! I know because it helps me.
You don't have to commit to a life-long exercise program to see if it works for you. Just commit to 21 days. Heck....even put up a calendar and count down your 21 days.
If you don't feel heaps better on day 22, go to the doctor and discuss your anxiety with him/her.
It's simple. It's effective. And, at the very least, it just may make you live longer.
Good luck!
