Hi Sandy, Welcome to our little corner of the internet.
I am so sorry for what you are going through. Your story is a familiar one to many here.
I know how much it hurts to call the police on your own child but you did the right thing. You have done everything you can to get your daughter help. Offering her help and pointing her in the right direction is the easy part and that you have done, unfortunately you cannot force her to accept the help that is offered.
You need to what you have to do in order to keep yourself, younger daughter and husband safe.
It's so hard to watch our adult children spiral out of control but there comes a point when acceptance is the only way we can move on with our lives.
This is something that you can get through. I'm so glad you found this site. You will find much needed support here.
((HUGS)) to you..............
