most people hate mondays, its cause you been doing what you enjoy and have had a break from the study or work routine, its only the first part of it thats a pain, go to school find something to study that you enjoy if its films, music, fighting (boxing, martial arts) see a teacher that you think may help you develop your interests. i know that school is a drag, but you really have to get stuck in believe me, you will be saying i wish i studied when i was at school, yes you have heard that before, but it will be true if you don't do it now.
plus mum may seem a pain at the moment and annoying, but you really don't want her to go to jail and she really does not want to go either, do you want her to go just because you are bored at school, get an interest you will find other people at school will want to know you if they see your making an effort. good luck metalmusic rock on
