The stigma around mental illness and neurodiversity. It's not like we're ableism-free, far from it, but being able to just say "I suffer from depression", or "I'm going to therapy" and no one really caring, or, in the best scenario, being understanding and supportive, has made things so much easier.
Not to mention that I wouldn't be able to understand a lot of my life and work on a lot of self-hate and preconceived ideas about myself without the lens of AuDHD giving me a bit of an out for me to get care.
