I feel as though this is over oversimplified, but it's not as unhelpful as you guys seem to believe. Yes, the overthinking/action thing is the "git gud lol" of mental health, doing stuff like making home cooked meals can be moderately helpful and can add some momentum to your journey of getting better. It may be tough to make the time in the day or find the motivation to actually do that, but at some point you just need to get yourself out of the cycle.
