Help to survive workplace until Access to Work calls my number?

I'm trying to get psychological practical help on how to handle Autism + ADHD characteristics.

For ADHD I've got medication but where I live they only allow one route: either only psychologist OR medication (as if a ND person can "choose" to need one OR the other)

My private insurance doesn't cover psychologist because I am neurodivergnt, and therefore a Premium tier is needed (as if ND is premium anything).

Raise request for Access to Work to see if I can get a grant for a coach / psychologist / whatever can help me.

Probably burning all the bridges at work because I can't handle 10s of "office politics faff" without calling it out (especially from people up in the food chain - gotta love hierarchy soooooo much like I love Unamused)

Even people that used to like me are slowly taking distance. Some others that don't like me that much don't feel bad at laughing at me anymore (sometimes I feel like disclosing just to make them "feel bad" - because everyone wants to be an angel when you mention inclusivity, right?)

What can I do? Anything anyone can suggest to help me survive the scenario? How can I keep my mouth shut without having to leave the room immediately to avoid calling a senior leader on their delirious ideas in front of everyone?
