Earlier quoted context omitted.
that's very difficult when you have a trait that others can't see, and therefore can't be aware of or understand, and much less empathize with. it feels wrong because you keep getting confronted with expectations that you can't fulfill. and you can't see others that have the same experience. so you end up feeling you are the only one.
I hope you can find your tribe, so to speak. My best friend is ace and has a large and supportive ace friend group. It is not a cure-all but it sure goes a long way....
as for the challenge of making friends, for some reason, growing up, i didn't feel the need, but saw the benefit of not being submitted to peer pressure. i took my outsider status and relished in it, doing things that few others of my classmates did. i distanced myself and sought friends in after school activities. and as i was able to make a few friends once i joined university i felt that, given the circumstances, things didn't go that bad.
the making friends problem i am addressing by moving out of europe and living among people who are more welcoming than the average europeans, and also by applying this key understanding:
being a friend means to care about someone. you make friends by showing that you care.
i show that care to everyone who crosses my path, and with repeated interaction some of these people become friends.
