I have a super amazing friend, they're neurotypical and we've been friends for 10+ years, since we left school. I have very few other friends with extrememly minimal contact, this is the one friend who I will see in person maybe every month which is a LOT for me.
We share a hobby, but in many ways we're also different. They know i'm weird and are incredibly tolerant and kind.
They're also interested in a bunch of different things than me and my stupid brain can't handle it. I get freaked out every time they try and share their interests with me. I try to never tell them to their face that i automatically hate what they like because it's irrationally threatening. I'm also very possessive and don't like that they have other friends or do other things. Great.. now I sound like a psychopath! But i'm honestly not. Again my friend doesn't know anything about this.
Does anyone have similar problems? Can anyone give any advice? How can I stop feeling threatened by someone being a normal person and liking perfectly fine things?
