I agree that most mental illnesses are biological/chemical, but they would be handled way better in a loving society focused on community and helping each other out. I know I've been particularly isolative these past few years (even pre COVID) and it's a lot easier to say "my depression is making me feel unloved, this is faulty thinking and I really am loved" when you feel loved during times of euthymia and can recognize the difference.

What saved me in my late teens/early twenties was finding and being involved in an extremely loving community (a program) where no matter what you said would be followed up with love and concern. They've saved my life numerous times. I'm extremely grateful for the counselors and especially the pdoc there. I wish I could find a community like that again, and I hope everyone else gets to experience something similar at some point in their lives. I don't believe "love cures all" but it sure as hell is an important piece of the puzzle.
