How do people keep friends?

Meeting people in real life is a completely different issue than online. I do struggle with making friends online now (it used to not be an issue lol) but right now I'm going to vent out my issues with making friends in person.

This is most likely a me problem, but I have a problem maintaining friendships. It's hard enough to meet people as a socially inept and visibly queer person. I have met new people during my adult life but once I'm out of a situation where I'm always seeing them in person (school or work) those relationships just die. I think it's because I'm really bad at texting people and making plans. I am a chronic overthinker and I assume when people don't make plans with me they don't want to hang out. Texting one on one with someone you're just getting to know is so hard, it's hard to gauge their tone and it takes me awhile to be comfortable. Starting friendships isn't the hardest thing in the world I guess, but maintaining them so very tough for me. I just have a bunch of aquaintences I follow on my inactive instagram account.

Installing apps or meeting people in the real life though internet is way too scary, but I feel like there's no other way to meet people besides going to work or school. Which I mean, I'm okay with that I guess. It's just limiting.
