Hello, 

When I have anxiety I sort of feel like I am gonna faint / have low blood pressure. Like, when my anxiety is at its worst, I have to lie down and put my raise my legs.

The thing is that I do not know how to breathe properly to avoid it since I do not know if I am missing oxygen or if I have breathing to much.....

Also, wearing a mask makes it worse because I feel like I can't breathe normally and it makes me focus on it.

What do you guys think ?
