It's ok to be weak without support structures, you'll be fine.
It's ok to not have friends, making friends is hard, 15% of the male population having no close friends is something you can work past, you'll be fine.
It's ok to have mental health problems, despite there not being any help or support for them, it's ok to let them take over your life from time to time, lonely men's bills pay themselves, right?
But you're men, you're meant to be strong, and stoic, and nothing is meant to phase you emotionally. You're allowed to cry, just don't be pathetic looking when you do it. Cry like a fucking man.
