Though I am an autistic adult living the US I can fully attest. It took 'mental health' over 30 years to realize that I am not bipolar, because I've never had a manic episode, and that they confused my anxiety with mania. Currently it's all I can do to ward off CBT and DBT, and to stop trying to reclass symptoms into some generic condition that they actually can treat.

Every single time I try to set a boundary it's defend the turf. Responses are a slew of "what are you doing that's so important" followed by "well why are you doing that?" Responding has never not been a complete waste of breath. I'm usually defending the healthy routines that I have created because dealing with their invasive species means dismantling as many of those routines as they demand like i should just be on board. Then they always try to gaslight me into having my difficulties downplayed, or they even argue that not only is something not a difficulty but they are not aggravating it.

The sooner the brain trust is able to do 'help' without messing with things like eat, sleep, poop the better. Even better if they realize that screwing that up is actually a problem.
