People always end up being rude to me for literally no reason

"Well, you shouldn't take things so personally. Their behavior is usually not about you, but them."

Then why is it ever only me huh? Why are they nice to everybody else yet rude to me when I'm nothing but kind to them? I haven't given them a reason to be mean to me. I'm not overbearing or creepy. I don't say rude or outlandish things. I don't talk gossip or drama. I don't initiate conflict or even participate in it.

Whenever I point this out I always get obnoxiously gaslit as if I'm asking the world to grovel at my feet. That's not it at all. It's infuriating that I even have to say that.

Having basic relationships with other human beings shouldn't take this much fucking effort. They always start off so wonderful then everything just eventually falls out of place and I can never understand why. I'm not even talking about having some big blowout argument. It's like one day I'm someone's prize then a few months later they get bored of me and toss me to the side.

I am 22 years old. I've had so many different friends come and go throughout the years. Girlfriends too. They all end up the same way. They just randomly start treating me different one day and it's never the same again. I don't even have to do anything wrong. It just happens on its own.

I don't even know why I still bother to mask. It's not like it matters anyway. It's like overtime people can pick up there's something different about me and they don't like it despite me being a good friend.

I'm not depressed or suicidal or anything. Just exhausted.
