I'm sorry to hear that, I think you can still make it in this world, but it will probably be less enjoyable without a few good friends. However, I understand. I had to rebuild social skills that I've lost over the years because my previous friend groups just fell apart, and it's hard to find people who get you. I think some people just have more common personalities and will make friends with anyone. But there are just some people I wouldn't wanna befriend at all. Mainly loud, obnoxious people who blast their ****ty rap music in public when no one else wants to hear that crap. Seems oddly specific but I worked with a lot of people like that.I've been told if I don't interact with people I won't make it in the world. I've had social anxiety since I was 12 years old. I'm 48 and still have it. As a result I don't talk to people and didn't learn social skills to make friends with people so I just keep to myself. I didn't make any lifelong school friends and no lifelong work friends my age. I just can't find people who get me. And when I do meet someone when they discover I'm not what they expect they don't talk to me again.
I think it would do quiet people good to try to make friends really for their own sake. But that doesn't mean more outgoing people have to pull people like us aside and make it their mission to make us friends, or make us more outgoing. Like why do they even care, it's none of their business
