Stress

Stress is the number 1 cause of my pain. I have RA and Fibromyalgia and stress in my life makes it worse. This week has been the worst for stress. My grandma collapsed at my house this week and was in the hospital until yesterday. She is now staying with us until Saturday and then will probably come back on Monday because she shouldn't be left alone for any length of time. I love her and love having her with us, it's just created more stress for me than usual. I think I just need to learn some new ways to deal with the stress so that it does not affect me physically. So, what do I do? What can I do to de-stress?
