My Mother just won't listen.

I try and talk to her and tel her what going on but she just won't comprehend what I'm saying, and when she asks me things, I've already told her, I just loose my shit because she just won't listen. I think she is scared of me growing up and she needs to realise that I'm not her and I'm not going to be, she went to one day of year 10 and that's all. I'm in year 12. I just wish she'd open her eyes and see that I'm not pregnant. I basically haven't even kissed a boy. She has no idea. I'm not going to be anything like her. My Mum is amazing it what she has come through in her life but its my life and I've gotta make my own mistakes and my own decisions.
