I want to go but my mum won't let me!!?

I want to go to university soon but my mum said im not going! I really want to go and study hairdressing but she keeps saying that im not going but i think the only one near me that does hairdressing is in Derby! but that is sooooooooooo far away and i probably would have to live there :( Its really annoying my because i want to be a good hairdresser and i want to be very experienced so going to university will give me another qualification hopefully. Why does she keep saying that im not going when its me that its for not her?! Thanks xxx
