As someone who was long term emotionally abused by someone “because of their adhd” and then later diagnosed with adhd myself, I think a lot of the confusion and messiness around this topic comes from genuinely bad-intentioned (or very young/ immature) people misusing medical language to stymie fair communication in relationships. Many people need accomodations, different communication styles, certain boundaries or conditions to function but they know how to meet their own needs without hurting people and apologize when they need to apologize. But, assholes who want to blame or harm or use others have adopted the exact same terminology as the nice people who just are trying to get their needs met in good faith. I think this is where a lot of the frustration about neurodivergence as an “excuse” comes from. It can be hard to tell which sort of person you’re talking to and unfortunately citing adhd or another condition is sometimes used to shut down someone else’s legitimate hurt feelings about something disappointing or genuinely fucked up that occurred.

it also takes time and maturity and healthcare to figure out what you need for accommodations, how to manage one’s emotions, how to have healthy conflict, etc. No one is perfect or born knowing these things, and not everyone communicating badly or unfairly is doing it on purpose or old enough to know better. People DO need to get the help they need in order to stop, though. If you do have adhd, it can also be messy and hard to discern honest important feedback vs bad faith or unrealistic expectations from others. Recommend therapy for sorting through that.

Edit: just wanna be extra clear that i am NOT saying the above is what you were doing!! Just offering a possible explanation for why OTHER people may be acting and feeling the way they do, and what I think some people actually mean when they say this. Tldr it may not have to do with you at all, lots of jerks are muddying the waters.
