Extreme anxiety all day

I cannot shake the anxiety. My heart is beating extremely fast and I tried everything to relax. I watched a movie, had pancakes, went running, listened to music, talked to my boyfriend.

Nothing is working.

I even tried to sleep, but just can't.

How do you guys deal with this? It's been so bad for about 3 days that I can hardly eat. I feel sick and nauseous all day.

What do I do?
