Thanks for the advice, I think it really helped! I've been feeling much calmer today, for the most part; last night and this morning I found myself actively talking myself through my symptoms and accepting them, and it worked tonight and this morning.
So of course I ironically ended up worrying that I was getting TOO MUCH AIR as of a few minutes ago. XD! I've been breathing very easily today in comparison, but I'm getting air bubbles in my throat and mouth, mostly the latter. Is this normal? I admit I've been drinking a ton of water and not eating as much as I usually do, and I used to drink caffeine until my symptoms started. Is this related? Does it mean I'm still hyperventilating or is it all in my head and safely ignored? XD!
