My mom is trying to saddle me with her debt without any benefits

Location: Currently, California, will be in Florida in less than 24 hours

Also sorry if the flair is wrong, it’s the closest one I could find

Years and years ago, under my mom’s guidance, I opened an Alaskan Airlines bank of america credit card with her as an account holder. It was fine for years, since she said it was to “help me build up my credit score.” We’d both use it, she’d pay it off, win win.

Only this year did I realize that (sorry for being sad) she has been narcissistically abusing me for decades. I’ve finally had the last straw and am flying across the country tonight to get away from her.

However, while I was getting ready to leave, I got an email saying “Your new card is on the way!” She apparently had requested a new card be sent to her (previously our) house. The account number is changed, MY card is now invalid, and her new one is going to be here in the next few days, so I can’t go to the mailbox and take it before I go, and I’m not safe here anymore so I have to leave.

My problem is that the card has $2,500 of debt on it. I tried calling to see if I could just make her the primary account owner and take myself off it, but I apparently can’t do that, but I can sort of shut down the card until I can pay off the debt and she won’t be able to add to it.

Im most likely going to do that, but my question is; is there a possibility I can sue her or something? I know her name was on the card, but requesting a new one I can’t have access to even though I’m the primary account holder seems wrong to me.

Any advice appreciated. If you got this far, have a lovely day <3

EDIT FOR CLARIFICATION: I am the primary account holder, but because of her actions, she has cut me off from my account so she could continue to accrue debt without me being able to access the card.
