Hi
Kade 
You've come to the right place for understanding - many of us were desperate when we got here, you are not alone.
Here's a great place to start with our site:
https://bpdfamily.com/message_board/index.php?topic=331689.0This article has links to many of our best articles which have links to more!
Posting here also helps many of us learn and find new ways of navigating our relationships with our children.
I see that you posted in 2019 that your daughter's fiancee cancelled their wedding. That must have been such a hard time for everyone. Is this the same person she lives with now?
How are you coping?
We look forward to getting to know you and supporting you through these times.
