Help me Pay some bills

Back in Febuary my mom died, and left behind a few bills, that of course are in my name...as when she took out a new credit card, she'd take it out in my name so she could keep my credit good. Since then, we have not been able to pay off the credit card bills for her eyeglasses or the bill for the new tv that we bought via Best buy. I am not sure if people know this,  but Lenscrafters, Best buy and Walmart credit cards are all owned by the same bank (Syncrony bank). I am into them almost 10,000 dollars, but if I could even just get 2,500 to pay back some of the money I own on the walmart bill I would grateful.

I used some of the money from the wal-mart card, to help my friend buy a new van (probably 500 dollars?),  so I am really good when it comes to helping people in need, but now I am in need... My sister has asked me not to run to gofundme to ask for help, but I worry about her a lot, as she works way to much, and has a heart condition and I can't handle the thought of losing another family member.  So this money, would make me sleep a little easier at night, knowing that she won't have to stress out so much anymore.

Thank you all so much,
Kirby Snyder.
