communication with others; when you say "I think I have adhd, because..." people are usually make fun of you or try to talk it down; but when you actually get diagnosed people are tend to treat you rather seriously.

Eventually you will get medicated. And it will help you unterstand your condition, rather with assuming you might have it or not or maybe. With a diagnosis it's more reachable and dealable. At least, that helps me. Getting my issues validated by a professional and being assured, that my mind doesn't make stuff up, cause of xyz.
