I recently had an anxiety attack out of the blue. Never knew anyone who had one. I'd jokijngly say things like "those aren't real" or "tell them to stop being anxious" if I heard about someone I didn't know having one. Mine wasn't what I thought they were. Hands unable to open, losing vision, my skull behind my ears was tingling, and almost like I got suddenly scared. 

Since then I've been feeling them coming. First it's the vision. Then the tingling on the back of my head. But when I feel that I try to stop what I'm doing and just sit. Idk what the hell to think about it right now. I cant drive anywhere. I found a Dr. So I have an appointment coming soon.
