Endorphins, better blood oxygen capacity, much better sleep, eventually better stamina in everyday life … all very tangible benefits of daily exercise. You don’t need a gym or equipment either. Running, walking, burpees, crunches, push-ups, maybe a pull-up bar can take you pretty far on their own.

None of this will directly fix all of your problems but it can better equip you to deal with stuff. A diet that is mostly fruits and veggies helps a ton too but that’s a whole other discussion.
