Hi lenzy,
Well I'm 18 and when I was 15, it was probably the toughest time I had growing up.. I understand why your daughters being like that cause that was me just 3 years ago..
I mean everyones different so I don't know your daughters reason but mine was stress from friends and school, and I hated when my mother would try talking to me. I don't know why it is, I know you want to understand what's happening with your daughter, you should sit her down and tell her to be honest with you and that you'll support her no matter what it is, cause maybe she's scared to tell you so she doesn't get in trouble.
If she doesn't want to talk to you, then just leave her to herself until she passes that stage.
She doesn't hate you, all teens go through that stage and its usually around that age.
Hope I helped a little.
