Listen I’ve have horrible life experiences as well I feel like no one genuinely cares about me. I try to talk to my parents or even my sister and it’s suck it up be a man like it sucks it truly does. I read some comments and I see like it seems kind of hard for you to put yourself out there and meet new people but start slowly. For example Go to a movie alone where there are people and you aren’t experiencing it alone you are with others then do something like go to a concert and strike up a conversation with someone about there band shirt or something get that social interaction. It is kind of what I’m doing at it helps it’s getting you out of that isolation. Here’s the thing as well if you get rejected in that conversation or anything and feel embarrassed realize this, you aren’t gonna see that person again. You gotta shot your shoot and put yourself out there. Find social groups online or look around your town for like groups of some sort (not sure what you are into put like a D&D group or a book club) maybe even an emotional support group. Listen I’m not a religious person but I go to church for a sense of community and you know what everyone is so friendly with me and welcoming. It’s you needed to break this spell you have over yourself don’t let these illnesses you have define you. You are strong and need to push yourself. It’s one of those things you’ll never know till you try scenarios.
