Thanks very much. I also have these Heads of Year that keep using my tics to gate-keep me from doing challenging super-curricular activities, such as Olympiads and things like running clubs or starting charity events, always reporting it to my parents as a "concern" and "taking on to much", despite the fact that STEM SMART is my only super-curricular, that I'm currently on A*AA, and that my peers do way more and they're completely fine with it. There was this one time I unfortunately witnessed domestic violence, and one of them at least cared enough to help me with my state at that time, but the other didn't even have the decency to ask how I was holding up, and the only thing she suggested I do was to "listen to positive music". Yeah, really professional info, right? And because of my poor self-esteem, I also have a lot of trouble saying no to people, and given everything I've told you, the only thing she said was to "just say no, it's simple".
I also sometimes get blamed for having tic outbursts.
