Why is it so complicated

This is a random rant, but I have such a hard time with people. A lot of times when I tell people how hard it is for me to decently socialize, they don't believe me and think I'm being overdramatic and say I socialize just fine. But I have to try so hard to even look at a person well having a conversation. It's hard for me to talk to people because I always end up really nervous whenever I do. Having decent conversations with somebody I'm not super close with really freaks me out and sends me spiraling for hours. "Did I say something weird?" "Do they not like me?" "I'm a total freak and now they know!" It gets so bad that I haven't made new genuine friends in a long time. There are maybe 3 or 4 friends I have that I can interact with without getting so nervous I want to break down. And there's nothing in specific that makes me dislike people I just get so scared at the thought of doing something wrong and freaking people out. Because I know to a lot of people especially people my age, I'm really strange and so I avoid talking about things I like which prevents me from genuinely bonding with people and that stops me from putting enough trust in them to talk to them. I want to make friends, but I genuinely can't hold a conversation for more than 10 minutes without trying to get out of it before my social energy sends me into full-blown panic. And it's not just making friends it's so bad I'm worried how I'll function in the future at all reasonably. Please if anyone can relate to this even slightly interact with this post so I feel even a little better. Maybe I am actually just dramatic, and teenagers are just crazy, and life is just out to get me for any possible reason.
