Examples:

Yesterday I was at a health evaluation for a driver's license. Everything went well with my physical health, but at questioning, my autism was bought up. I was accused of needing help with learning in primary school (despite of my grades, that were usually B (I know, I'm lazy)) and now I need a psychological evaluation.

When I started high school, most professors infantalized me, but later stopped after I proved myself (ok, some didn't stop, like the slovene teacher and the sport teacher/coach).

When I meet someone new, they always think I am intelectually disabled, before proving otherwise...

Why is this happening?

Edit: It means a lot to talk to people who support me trough this (even if only on the internet). I took a psychological evaluation today. It included an iq test like form (easy, but didn't finish the whole paper), questionairs and some cordination tests (that in my opinion I was bad at). Just waiting to get the results. Hopefully I'll pass, but I can't really do anything if I don't, can just maybe try somewhere else in the EU (i think).
