If I was myself all the time I'd always be silent

I'm so stressed, I have a sociology exam on Friday and nothing seems to be going right. My mum told me she will ask me to move out if I carry on the way I am and not doing as she tells me, pathetic. I dyed my hair red last night and it didn't work because my hair is too dark so I think I might pre-lighten it but I'm not sure yet. Luna came out for a bit today, I also tried to get my big boy Jasper out but he wasn't having it haha.
