I want to live with my father?

I'm 14 and i live in England with my mother. My mum is verbally abuse, has a very shorty temper and often physically lashes out, and i cant take it any longer! I want to go and live with my father, but he lives in Ireland. this means i would have to leave schools and move to somewhere where i don't know any one my age! and i am half way though my GCSE's which makes everything so much harder --- do i have a choice in what i do???
