I too have been on a health scare roller coaster this past year and a bit! It is hard to control emotions sometimes and hard to find coping strategies. It will take time, but you will find something that works.

Be open to suggestions.

Have you tried deep breathing?
Breath in deeply thru ur nose and focus on your breath filling your lungs lifting your chest up, hold a second, then slowly release your breathe thru ur nose, slowly, feeling your tummy deflate towards your spine, focus on your breathe. Do this ten times. As often as you need to. I hope you try it It's free, no drugs, no where to go!
