For the past month ive been having super bad anxiety attacks at least 4 times a week for no reason what so ever. I literally have never had it so bad like this it gets very bad to where i have to lay down in front of a fan until it passes or I fall asleep, I get a really tight chest sweaty dizzy and just can't breathe. Does this happen to anyone else? This is my 4th pregnancy i have a almost 5 year old and 1 year old and i never had anything like this. Can someone give me some advice about what to do?
