it's not about people liking you lol, being a people-pleaser is the last thing i'd want anyone to be. these are just couple things that keep most people grounded, enough to serve as a baseline in keeping them sane and functional. it's fucking hard and almost inhuman to tick them all at the same time, but it's worthwhile to give some of these things some time every once in a while.
it is not about being liked, it is about feeling better. walking have always been my to go solution when I have the blues (not full blown depression though). I am not saying it will fix all your issues, but it MAY improve them a bit and it won't make them worst. (not sure if your notion of health included exercice)
