I'm honestly going crazy. My brain will not stop. I'm even ruminating over if I can stop ruminating or not. I don't know how it's got this bad but I don't have therapy until next Thursday and I need advice on how to keep sane until then

Dangit. I cycle like this too! Do you have anything you do in order to stay busy? (Chores, errands, drawing?)

I can, but my mind can still ruminate

Yes I know this all to well. I start obsessing over thoughts, then ruminate on the fact that I'm thinking thoughts. It's weird. Are you taking any supplements or medications?
