This is me on the weekends for sure. I feel like I’m wasting time even after I’ve cleaned my room, washed the dishes, done the laundry etc etc. Journaling, and keeping a to do list helps a bit, just lets my brain remember ‘oh yeah I’ve done all the important stuff’.
You’ll almost certainly be alright, keep track of your status and call a nurse/teladoc to see if you need medical assistance. The most important thing is you stay calm and don’t let your panic take over.
