panic attacks are petrifying especially when coupled with stress, first God Bless you and its not easy. Its damn near difficult and especially if you are not used to them and the feelings they have. Best thing to do is see if you can find a therapist you can talk with, second solution is weed, third is just breathing and getting through that moment, it is all it is a moment. Not easy but it can be done.
you are good soldier, we all have those times, but remember baby steps and be kind to yourself also. we are dealing with a lot of info and stress that others are not even aware of yet. God bless you and we will welcome you back to the front lines when you are better. take care of yourself.
