I mean people who did/do have a mental health/mood disorder diagnosis but no developmental diagnosis or learning disability. Did you get put in special education classes?

I am just now realizing (I’m 22 and haven’t been to any school since I was 18) that maybe that wasn’t the right place for me? I was in special-ed from 6th grade onwards and I never learned anything new past that point. My mental illness did effect my learning but i had no real learning disability and the fact I wasn’t in math classes for my grade was why i never learned it properly. I guess its called ‘special education’ for a reason and I always loved the people that were there, i never felt like I was being talked down to- But it just seems like I was put there so i wouldn’t burden the main teachers, I was doing work sheets that said 3rd grade class work on them in high school. I was told if I wanted to go to prom I would get a guaranteed date to go with me. Maybe thats what its for and I was just the only child with a mood disorder. Anyone else have that same type of thing happen? I’m extremely curious.
