Has anyone ever experienced constant anxious butterflies in their stomach for days that you just can't get rid of?

My depression and anxiety have been really bad lately, and I am getting more and more anxious about my depression because I panic that I'll end up back where I was before, psych ward or worse. It gets so bad my heart pounds and I feel like I could physically throw up I just want to crawl out of my body.

Trying to distract myself seems to be the only thing that helps, although that is extremely difficult!
