There's a couple different things with this so I hope it make sense..

This is my first year of high school, and towards the beginning of the year there was this teacher who I thought was pretty cool, let's call him Mr.P. A couple months in (November-December) he started saying weird and rude things. It was rather off-putting, so I wanted to discuss it with him and let him know how I felt about things he had said. Well, that didn't end too well. We didn't talk at all for a couple months. Now that I'm taking his class, we kind of have to talk. Anyway, towards the beginning he was kind of cut off (which I was fine with). A couple days after starting his course, I ended up having a really bad anxiety attack, which a couple of the other teachers knew about. I have a feeling that the others know what happened, because all of a sudden they're being extremely nice, including Mr.P. He's always telling me to relax and trying to give me reasons not to stress about things. He's making a lot of things easier for me, which I do appreciate, but at the same time it bothers me. I don't want kindness just because the fact that I have anxiety is known and that's what it feel like, as all of it started after that incident. Continuing on, I was talking to a couple of my friends who took his class last semester and they said he's giving me obvious special treatment (with making things easier). Something that bothers me, and I can't seem to shake the thought, is that every time we talk I feel as though he's going to go back to being a jerk. It makes our discussions, for me, nearly unbearable. I'm always bracing myself ready for an insult or back handed comment. Constantly worrying about this is adding onto the anxiety and I don't really know what to do about it. Right now I'm just trying to ignore it, but people are confused by that as they believe the exact same thing to happen.
Does anyone have advice or something? I'd appreciate it greatly
