Hi Jo,
You know something that's forgotten a lot is deep breathing. I've noticed since I have taken time out in the mornings and just sat and breathed deeply, it has helped a bit with the calming effect. People don't realize how shallow they usually breathe on a daily basis, especially if you have not been feeling well. Mouth breathing can cause a lot of problems such as dried out lips, scratchy throat, hoarseness etc., and anxiety can make it more pronounced. Stress and not feeling well are an awful combination. I know. My heart goes out to you. If you can, try the calming, DEEP, relaxing breaths. Get the oxygen pumping to those little cells and brain. Hope this helps a bit. I agree with Diva as well about having some fun. And remember, your poor body has just waged a major battle fighting off the ickies. Give yourself time to recouperate. It's normal. (lol sorry, I'm a mom. I always have advice about colds.)
Good Luck! Arteest
