Canadians, advice?

Wondering if anyone has gotten disability tax credit from their ADHD diagnosis, or tried.

That's my whole question but I guess there is a character minimum...

I have a pretty official diagnosis from like 2022 or 2023. It worked to secure me more funding from the national student loan centre.

Tried to bring it up at H&R Block the last time I got my taxes done (I won't say when 😂) and the lady poo-pood it immediately saying the disability had to be really severe. I feel that I could truthfully make a case that my disability is actually quite a lot.

Let me know- thanks in advance.

DMs are welcome!!
