This wasn't malicious per se, but I had an English teacher/school counsellor who suspected I had some sort of learning disability and treated me like an idiot because of it, but like in that sort of "poor you let me help you" way that's like really condescending that ended up really hurting my self confidence.

If I struggled with something for any reason, I was given something easier. If something I did conflicted with what she thought was correct, she would sit down and "help me correct it" because I think she seemed to think it was I guess an autism thing or something, which meant she spent a lot of time (usually taking me out of lunch break) trying to "correct" whatever she thought I was doing wrong. Which was exasperated by the fact I was an expat from the Commonwealth and she was an American so half the time they were just, cultural things. My dialect? Incorrect stop being non-rhotic and dropping your Ts. Handwriting? Oh dear this isn't D'nealian you're going to have to relearn this. Needed something repeated because I didn't hear it? Let's sit down and go through each step one by one in simple English so you can understand it. Social issues were the worst because she'd try to explain how to be friends with someone like I was five and try and push me into other people's friend groups when I did not want to do that.

I know she wasn't being malicious and like, she was right - I did have a neurological disorder, and she was the only person who noticed before it actually started affecting me negatively. But oh my god she was so condescending and made me feel like I was so stupid and absolutely fucked my handwriting. Also people noticed the attention she gave me and made fun of being for being "retarded" which was fun.
