Hi rethomofBPD,
I'd like to welcome you to the community. I'm glad you reached out, as you found a great place for support.
I can understand your feelings of anger. It looks like your daughter has had a different view of the purpose of the credit card. For example, an "emergency" for her might be something that is non-essential in your eyes.
Are you planning to cut off this credit card, too, or do you want to explore ways to communicate about it and keep the conflict down?
This site has tons of resources and tools that can help. And members who understand what you are dealing with.
Keep posting. We're here for you.
