Accept yourself. There's no way to change how you are, so you might as well be happy about it. The Autistic community is full of lots of different people who can help you with some of the more challenging parts of living in a world that doesn't accept us, who all have their own experiences with whatever it is you're worried about.
(If you aren't Autistic yourself and you're looking for how to help someone who is: listen to Autistic people. We have years of lived experience and probably know the reason why your loved one is struggling with a certain thing, because we've struggled with it too.)
