I'm Scared in I Worry Too Much ;-;

I have to go back to school soon but it was recently that I had come out to my mum as transgender (FtM). She said that she will think about letting me change my name on the register but annoyingly, I attend a british school meaning I am most likely going to get bullied. I’m not just scared about me getting bullied, my friends could get bullied as well. My younger brother has also just left primary and is going to my secondary school, I’m scared he might get bullied because of me. I don’t know what to do, I’m scared of even leaving my house but now I’m going to have to back to a school of hundred of homophobes and transphobes. I just wish I could disappear, I don’t like living in a world where 99% of people are judgemental and horrible. Plus I haven’t done any working from home meaning I’m months behind on work.
