Hi Paige and welcome!
Do you regularly practice breathing and other decompression exercises?
We have some great ones in our Resources here. There may be a few new tools to add to your belt.:)
I also have a favorite breathing exercise that I have found so helpful with the constricted breathing feeling! It is not in the above mentioned Resource Guide, but I will gladly post it at your request.:)
Keep talking with is if you find it helpful...support is key!
