WIBTAH for (potentially) refusing to go to college or uni?

Hi all. So currently I’m only 14, and I have lots of time to decide, luckily, but I have been doubting if I will go to college or uni at all. Basically my mum wants me to go to college or uni desperately, as she lived with her parents for a long time without getting a job or further education. It was not until I was born she left her parents house. What I’m saying is, she doesn’t want me to potentially end up like her (working 3 jobs and on benefits and we still live pay check to pay check). So, I’m not saying I don’t want to go, but many factors restrict me and I will start with the main one. I don’t have my own bedroom. Aged 14, I don’t have my own bedroom, and even though my mum has promised we will eventually move to a bigger house (which would make this post useless) I highly doubt that we will move because I highly doubt she can afford. The reason I need my own space is because I’m a teenager, and need privacy and quiet, my younger brother is a nightmare who is never quiet, and doesn’t clean up at all, we never get along. I also need a place to study, which is already impacting my GCSEs, as I rarely do homework due to not having my own space, and even for college I wouldn’t be able to study at all. So, I want to tell my mum I’m not going to college or uni if I don’t have my own room, but WIBTAH?
