Im begging for your help (10points) i ******* HATE my family!?

Im 16 and going through a really tough period, my most important exams of my life have just finished after preparing for them for a good 3 months and im also struggling to complete tonnes of work im either behind on, or i need to do by the end of june/july. Unlike other 16 year olds i have the privledge of school and college where i learn construction, which is requiring a lot of work right now. Let me take you back 1 week ago, where i have until the end of june to finish 4 SCIENCE COURSEWORKS WHICH I BARELY UNDERSTAND, AND ABOUT 20 BUSINESS STUDIES COURSEWORKS WHICH HAVE TO BE ATLEAST 600 WORDS LONG EACH AND WOULD TAKE ME ABOUT 3 HOURS EACH. However i have until the end of july to to finish my college work which can be done in 1 solid week. My College is phoning home telling my mum i have to come to college to do the work, however my school teachers are telling me to come to school to do work and catch up. So the obvious thing would be to balance the 2...i have now OFFICIALLY FINISHED College and School however the work can still be completed late. I would usually attend college on a wednesday and friday but now i have the option to go anyday i want visa versa for school. So everyday i think to myself whether i would benefit to go to school or college the following morning and its always a clear decision, considering i have till the end of june for schoolwork and the end of july for college work its obvious what priority 1 is (school). But my college have told my mum i must go Wednesday and Friday to go complete work (and you know how teachers exagerate to parents) they say its imperitive but it really is not as i have till the end of july whereas i have other work needing completion, so my mum picks sides with my college teachers and forces me to go which is only making my schoolwork deadline get even closer. I get into big fights with my mum who is caring for my nan (so its me my mum and my nan in the house) because she has no clue about my WORK and whats best for me and the only reason she is pushing me to go college is because she does not want to look like a bad mother on the phone to my college, so we argue and im trying to stress what i know i should do and she starts going into other subjects calling me "lazy" etc, which has no relevance to the situation, if i go to college one day i can turn up whatever time i want to, so i take advantage of that by sleeping in an extra 2 hours. My nan who is just as ignorant as my mum just defends my mum even though she has no ******* clue what we are talking about and thats pisses me off more and they get abusive so so do i. And i admit im very argumentative but its because i like to get my point across and make sure the listener understands me and why im choosing my actions but these 2 ignorant people are always butting in etc. My mum and dad are divorced and they have four kida toghether including me, my dad and his side of the family are quite intelligent and i take after them however my mums side (who im now living with after my brother was not happy about me living with him and my dad) are thick as S.H.I.T. i am constantly proving them wrong but they always have an answer but never listen to me, they have no clue about how my school and college work and think im being lazy and argumentative when really im up all night stressing an struggling to complete work on time and panicking. Ive been to councelling before with my mum and im not going back again. Sometimes i feel like running away and one minute i love my mum the next she is sooo ******* stupid i feel like punching her. Today i get home and i see my nutcase uncle sitting in the living room and he shouts at me for being rude to my mother but do they not see she is always first to tell me to shutup and piss off, i overheard my nana saying im a waste of space and im going to turn out like my low life brother which im not. I dont knwo what to do or how to put them thick shits in their place, they have no clue and they are so ignorant and try bullying me, im sure other people understand what its like arguing with thick people, its impossible. i need some help as i feel like giving up and doing something crazy, please help.
