Help with dads medical bills

I hate to do this but asking for help. Dad has been in the hospital for a month already and has been transitioned to Acute Care.  They say he will be in Acute Care for at least a month and then transitioned to rehab. Last time he was in the hospital for pneumonia it was for three weeks and then transitioned to rehab for a month. The final bill after insurance was a little over $13000. I spent hours in contact with the Va and other services to try and receive help with the bills and finally had to take out a loan to cover the debt. Dad is on a limited income and what he gets pays for his medicines, his normal office visits, his personal items, and to pay back a debt to the VA for funds he received they say he wasn't entitled to. So it has been up to me to cover the remaining medical bills. This year between moving and I had two surgeries myself as well as a loss of income and damage to the dojo has left me tight on the budget so it is becoming clear that I may not be able to cover these bills. I have met with financial advisors at the hospital and Acute Care and dads estimated final bill may be around $25000. It is with a heavy heart that I am asking for help since normally I have things under control and usually can manage the extra billing that comes in. I have cancelled attending some events as to get the funds back to help with things but it is still not going to be enough. Please donate whatever you can to help the family pay dads medical bills. For those who know my dad he is 88 years old and treats all like they are family. I know everyone is having a hard time now but if those who can help would it would be much appreciated.
