Hi
monafone618 
I'd like to join
Faith in welcoming you to BPD Family. As she says, you've come to the right place to get help.
I'm so sorry to hear of all the difficulties you are experiencing with your DD - false statements to the police, unpredictable rages, and expecting you to foot the bill for her expensive tastes. It does sound like a nightmare, indeed. You will find many other parents who can relate to what you have shared. You are not alone.
I also echo what Faith has said, you deserve to have a life too. It seems like you've really gone above and beyond for your daughter. We have tools here that can make things better for you, to help you get that life of yours back. A good place to start is the thread pinned to the top of this page,
HOW TO GET THE MOST OUT OF THIS SITE. It's got some of our best articles all in one place, even one about Boundaries as Faith suggested.
The best thing we have here are lots and lots of members who are traveling similar journeys. We support each other, learn together, and encourage each other to take very good care of ourselves. Please keep posting, sharing, we are listening. You don't have to do this alone.
Again, Welcome to the family
