Long story short, I (18M) am a super lonely guy. I chose to focus on myself my entire life and consequently never had any actual friends or relationships. But this past year I've made some realizations about myself and really want to develop a social life and start relationships. But... I'm introverted so idk how to do that. Most suggestions I've seen say to meet people online, or to go to parties/bars/clubs. But online stuff has been a waste of time and parties/bars/clubs aren't for me... I just don't like those kinds of things. I'm not really a nervous person, but I just don't know where to meet cool people and I'm lonely. What should I do?
