Teacher can't be bothered to listen to me talk

Teacher can't be bothered to listen to me talk There is a specific teacher that is very mean to me in a very passive way. Sometimes she tells me something in class and I answer, but when I get stuck in the middle of the sentence she just ignores me and talks to someone else leaving me talking alone like an idiot. Today she asked me a question, didn't listen to me at all and left while I was still talking. She didn’t even look at me in the eyes and said goodbye to the whole class while on her way out. She just completely ignored me, like I wasn't there. I know it's small things but it makes me feel like I'm invisible
