I have found over my 79 years of life that metal health is just as important as physical health. They both play such a critical role in our lives and affect each other drastically.

I do take medications when needed but it very rare. I find that my anxiety and stress goes way down with exercise. Of course you need to check with your doctor before starting any exercise but I found exercise relaxes me, tires me out, and when come home calm.

I do water aerobics 5 days a week and totally enjoy it. We do excercise to music and you can work at whatever level you want to. If I miss a class I can feel the anxiety and stress.

Exercise not for you. Try finding a hobby. Many do this also. Anything that gets your mind on something other than your anxiety, stress, and worry is going to help. I read a lot of non fiction books. I read that FDR would work on his stamp collection daily for about an hour. He was under so much stress in WWII he found it took his mind to a calming state. He also swam in pool and went to hot springs GA.

Have you ever taken Yoga. I did chair yoga for years. I don't anymore because they changed the day/time for the class. But I remember a lot that I learned there. One was the calming breathing. You breath in through your nose deeply and slowly. Then purse your libs and breath out slowly and deeply. Keep doing that until you feel calmer. I should not be done fast as that just causes stress.

I also read a lot. It too brings my mind away from my medical issues and other mental stress and anxiety.

AFIB can be mentally challenging. Finding medications that work for you is a job in itself. And also finding activities that lesson your anxiety and stress is going to help. Anything you would like to do, try doing it. Find something that makes you smile and your anxiety is going to go down.
Good luck!!!
