Hmmm, you said 'mum' which is traditionally not an American way to say mom, so I'm guessing you are out of the US? I can only speak for what I know here, but maybe you can look into there. If you can get in with a t or pdoc, you can have them contact the school. By law, schools have to do certain things to allow children with disabilities to recieve their education...even if that means providing a tutor or assiting you mom with home schooling. If you were out for months because of a physical illness, you would (hopefully) recieve your classwork and instruction. With the internet and all other types of communication, it should be fairly easy for your school to use something like Blackboard and drop your assignments on there. If you can't get a definate diagnosis I would still encourage you and your mom to talk with the principal of the school, the school board and teachers about the issues that you have. Maybe a transfer to a smaller school or a private school may help, also.
