Skeksi - Progressive Muscle Relaxation, I'll have to do some searches on that. Sounds promising.
Unfortunately I don't have a smart phone. Which is sad because my ex wanted to buy me one, but I wouldn't let him until he had his other bills paid off. Could've worked to my benefit - lol! The app that specifically coaches relaxation breathing probably would've benefited me greatly.

I'm hoping to get one on sale during Christmas.
Thanks again!
