@TheBreadmonkey@beige.party Hi, fellow AuDHD here. You're not broken. You have a brain that works differently than the system we're forced to live in can adequately deal with. (Or is willing to, because accommodations are for them, not for us, at least not long-term.)
I'm so sorry that you're dealing with invalidation both personally and in a wider social sphere. I know it's frustrating and more than that, I know how much it hurts.
If I can gently suggest trying to find AuDHD groups to touch base with once in a while, it might help you feel less mentally isolated (because that's the aim, I think - to make us feel like what we have isn't real and to burn ourselves out trying to fit into a mould that will break us).
I know I can't do anything about the wider social issue, or about the people in your personal life that are, to be blunt, rude as fuck about your lived experience... But I can extend a "hey, you're not alone in this, your diagnosis and needs are valid, and while we may never be friends, I'd like to be friendly with you" hand.
Again, I'm so sorry you're dealing with this with such a new diagnosis. If it were 20 years on, it'd be a lot easier (I can say this from personal experience), but since you're still probably unraveling the "what's me, what's autism, what's ADHD" at times, you're getting a one-two punch at a really hard time.
