I am a 15 year old girl,l in a house where I get verbally abused by my sister to the point where I start to bash her. That's not who I am but after so much abuse from her, calling me names and making snappy comments I just blow up and end up hurting her. Its not the right environment for me. How do I get into foster care? I'm sure my mum and sister would love to have me gone and they would be better off without me.

I seriously doubt if things are as bad as you say. And foster care may be much worse. But what you need to do is talk to a counselor. A school guidance counselor would be a good place to start. If things are serious enough, then you may find yourself placed with another family. Or you may be helped with tools to cope with your situation.

well I think you should ask someone to help you get into foster care but remember there's no turning back
my friend got put into foster care and she hates it ! Its way worse you get put into some random family and
you might get put into old people hands ,or strict like my friend so don't do it you have 4 more year's you can do it
or
talk to your mom or dad about it or your grandmother/grandfather or Nan
hope this works
MERRY CHRISTMAS
