As someone who’s also diagnosed with depression I’ll at least say this:
It isn’t inherently a cycle of cruelty and despair. I mean the fact that people tell us otherwise means that, at least for them, it isn’t. It’s sad but there’s a lot to life that we’re just missing.
Edit: Idk what you’ve tried but 10 years of meds never solved anything for me, but psychedelics came close. I never appreciated life more than when I tried shrooms.
