I randomly get tightness in chest and under rib cage it makes it difficult to breathe then I panic because I feel I cannot get a proper deep breath . I also get unsatisfying yawns or incomplete yawns which also effects my breathing. This happened for a week straight last winter somehow I overcame it, I woke up in the middle of the night and couldn't breathe and it's been 3 days of feeling like this now. I can't handle this feeling it's very scary and has been bad enough to make me want to go to the hospital but I haven't actually gone to the hospital. I don't know how to fix this
