How do you cope with chronically being misunderstood?

Hi. I'm pretty new to this sub, I try to avoid posting online but the lonliness has gotten pretty bad recently and lurking here the past few days has really helped so I though I might as well make a post and see how it goes.

It feels to me that my disorder inhibits me socially most of all, though I'm sure the other diagnoses don't help. I just cannot seem to get my point across to anyone. I can spend years in therapy learning how to talk "correctly" and still be misunderstood at every turn. When it's not my wording its how I emote. When it's not how I emote, it's how I think. And it leads to a lot of isolation because honestly? That much rejection and failure wears me down so much that I go in cycles of wanting relationships and avoiding them at all costs because it just doesn't feel worth it to me. I get told a lot that I need to be accepting of this fact or whatever but no one seems to get how painful it is. I can't just "move on" when this is all I experience when I interact with others. Hard not to be socially anxious when every attempt to "prove my thoughts wrong" ends just as badly.

How do you cope with this? I'd also be open to hearing other peoples experiences because honestly I've never met someone who struggles to the degree I do (not that I've met anyone with my diagnosis before). Is it possible for me to form deep connections with anyone?

Thank you

Edit: sorry for any spelling errors I'll fix them as I go but I can be pretty bad at it
