Hi, I'm facing breathing difficulties sometimes, all of a sudden I can't breathe it started recently like few months back, initially I used have when I'm on period, later for the past 2times I had same pblm when I'm not on period. Recent one was in the morning I had breakfast and was working, suddenly I couldn't breathe and I struggled for 30mins later I started to listen some music and tried to calm myself down then I was okay, what should I do, I don't understand if it was panic attack or just like suffocation.
