Find out why she hates you? It's always hard hearing bad thing about yourself, but yknow maybe you come off like an arse and don't realise it? Anyway you can't "make" someone like you. Developing a crush on someone isn't something you have active control over! Life would be so much easier if you did!
You can't make someone like you. How to get over it? Get involved in other things. Friends, School, Family a job. In time you'll get hooked on someone else.
