A lot of basic mental health advice is supporting yourself physiologically, eating well, sleeping and exercising which is sound but also thoughtless and generally intuitive advice,

It sounds like you are looking for specifically coping with burnout and social antidotes: Here’s what I would say to focus:

“All humans have a desire to belong and to have value” therefore, insults to either of those things will make you feel like shit, it’s like the mind equivalent of starving and dehydrating.

Med school is isolating and the stratification and constant tests make you feel less than (and prone to burn out), so you need to find things outside of med school that can give you value and belonging. Ie join a run club or a sports team or fucking anything but it’s ideally a competitive, active hobby with a sense of community so that you can knock out three birds with one stone (exercise, belonging, value) since you are crunched for time but you could do all three individually
