onionknight I think I understand what you are talking about. I can get stuck in a loop of thinking that will prevent me from getting anything done except worry. I have been stuck there for days.

To get out of it, I take extra good care of myself. I make sure I am eating, I talk to friends/family (not about how I'm feeling- just talk), sleep as much as I can, and do somthing relaxing but that takes concentration- like reading.

If there is somthing actually wrong that is making you worry, then tackle it. Get it done and over so you can bring yourself back down. Easier said than done when your worry is sitting on your head like a bucket.

I also take meds. Those help to keep me from getting in that anxiety loop. Have you seen a doctor?
