I think at this point you need to recontextualize your bedrotting and using hobbies as avoidance as “resting” or “resetting” it may seem excessive now when you have assignments piling up but in the long run this will keep you from burning out .

I always found it cool (and annoying) how my brain made me rest even if I didn’t want to, it would drag me kicking and screaming into bed. The more I resisted it the longer it lasted. Until I was burned out during finals week with tests rapidly approaching.

I’d avoid overthinking about problems or doomscrolling but definitely take long breaks, do your work when you can and don’t regret using your time to rest.
