AITA for being mad at my mom because she refused to get me adhd tested for nearly 2 years?

AITA for being mad at my mom because she refused to get me adhd tested for 1.5 years? For context, I’m 17 and ive been wanting to get adhd tested for nearly 2 years at this point.

but every time i bring it up she either says she’s going to take me to get tested in a few months or that I don’t have it because ”nobody has complained about you” or “you’re not stupid”. it’s just been an endless cycle for this for the past 2 years where I ask and she either tells me to wait or tells me there’s no way I have it. and it’s getting really tiresome.

so after asking her to get tested a couple days ago, and her saying no again, I kind of got really angry and shouted a bunch of things to her (its not like slurs or anything). and she hasn’t been talking to me for the past few days.

the thing that really made me mad is the fact we can actually afford it. Hell even I can afford it by myself but it’s not legal for me to get tested alone.

so yeah aita? sorry if it sounded a bit rambly
