Anyone else get through the day basically perfectly fine, but then the moment you're alone with your thoughts, the alarms start going off?

I'm currently in a rehab clinic while covid is running through my home. They dropped me off two days before becoming symptomatic, and I was definitely in contact with my brother who brought it in. I've been swabbed three times for PCR tests, with all coming back negative..

I am just *so* scared, and the moment I'm supposed to rest, it's like every single thing in my body that tells me when something is wrong, goes off. It's easily my biggest reason for using right now, and I can almost guarantee I will use if I get covid. My main doc are benzos, so I guess it makes sense from a coping mechanism stand-point, but I'm just so done feeling this way..

I just want to not have to worry so much. I feel like I can't keep on living and feeling this way. It's just all way too much
