Sometimes I don't think teachers do this to be spiteful, they do it to be fair. I remember being the kid who always put their hand up to answer questions, and once I noticed my teacher was ignoring me I asked them during break why they kept doing it and they told me it's because they want to give other students a chance. They won't really learn if one person answers the questions for them. This was in primary school... You're in college, and as you keep banging on about being a "young adult" you should have taken that approach. You're trying to be a victim in a situation which really isn't that serious. If you don't like the way your teacher is treating you, you have every right to complain and demand changes, but don't you dare jeopardise other student's education just because you're upset.
