Can someone be fine then out of no where anxiety hits them with fear, worry, sweaty palms, and then ocd intruaive thoughts all randomly?

Yep, it happens to me many times a day, what helps me is to recognize and label those feelings as part of ocd or anxiety, then let them come in but knowing that I don't need them anymore, they just come and go by themselves.

Thanks you guys

happens to me way too often

Me!
