Sometimes when we get stuck in an abusive relationship, we start to believe that we don't deserve any better, that is maybe just our lot in life...

I don't have practical advice for you on what to do and how to do it, but I want to say that you should never fall into the trap of believing you can't do better... You can and you will.

I agree with almostangela, the support of family and friends is very valuable at these times... you need someone to help you through this....
