Just ignore the people who try to deny you exist and that your experiences are real. A wise anon once told me this:
Don’t fall into the trap of thinking there’s anything you could do. Even if you managed to reach the goalpost they claim would make you respectable, they’d just move it as soon as you got there. They don’t hate you because you’re unacceptable, even though that’s what what they want you to think. They hate you because they don’t want things they disagree with to exist. The only “right” you could do by these people is to just not exist.
