Elderly mother's credit card payments taking half of her Social Security

I just moved my elderly mother from Texas to California after her care takers were charged with elder abuse. I am now her Durable Power of Attorney and I'm trying to get her situated with MediCal and into assisted living. I have just found out that she is making the minimum payment on three credit cards with extremely high interest taking over half of her Social Security check. She will need her entire Social Security check to go towards the cost of assisted living. I believe the credit card companies have taken advantage of my mother by charging extremely high interest rates. One of the credit card companies, Chase, closed the credit card after my mom called to try to lower the payment. They said it was because they received a message from a credit bureau, which could not have been true. Is there anything we can do to charge off or file for bankruptcy to make these go away?. My mom simply cannot afford them. Thank you
