Welcome [USER=19816]@wearyone[/USER]
I am so sorry your daughter is stealing from you. Under these circumstances you have every reason to feel hurt, angry and betrayed.
Your family history sounds difficult and complicated. Remember you can only do what you can do at this point. Your daughter is an adult responsible for her own outcome. Your intentions are good.
I'm going to move your thread into our Parent Emeritus forum where parents discuss issues with their children that are over 18. There is a lot of wisdom shared there. Hopefully others will come along and offer you their support.
Hang in there. You are not alone.
