How do you sit with anxiety without ruminating?

How do you sit with anxiety? I wanna check my pulse over and over again. I dunno what caused my anxiety. Now I am just sitting here. Ugh! I feel crazy!

Hello everyone! I’m starting to recognize when my thoughts begin to spiral, when i’m seeking reassurance or checking. But I still have the sense of uneasiness and anxiety. I was wondering what others do that allow them to move forward with their day when they realize this? I don’t know if I’m making sense, but what are ways you pull the focus back to the present and yourself? Like besides saying “maybe or maybe not”, more like what do you do with yourself after you recognize the thoughts? I feel like I’m at a “now what?” and don’t know what to do with my anxious energy. I’m trying to find something physical to help me so if you also have any hobbies or interests that help I would love to hear it.

I've been doing well the past month in cutting down on compulsions and have been feeling better however, last night I had a set back that carried on into today. I had gotten very poor sleep (4ish hours) and then something triggered my memory. I think with the sudden anxiety spike and lack of sleep I didn't have the strength to ignore my compulsions. Last night and today I've realised I've gone back into rumination and mentally reviewing the event excessively again and comparing my situation to other people's, but most of the times that I start going down these rabbit holes I don't even realise I'm doing it? Also been fixating a bit on the fear that I've ruined my progress and that I will fall back into the deep end of it all again, that I have done so much work getting myself out of, although trying my best to not be too discouraged. Does anyone have any advice on how to deal with rumination more specifically?
