Liv's knee reconstructive surgery

We are devoted Christians to the Gospel. I am a single mom disabled with multiple autoimmune disease and disorders.  My 16 yr old daughter just had reconstructive surgery on her right knee and it was more than either of us thought it would be. Lately, I have been working some part time hours to make ends meet but, she can't even get to the bathroom without me. After surgery the surgical center estimated an out of pocket of around 5000 dollars.  Then after 6 weeks she needs 4 months of rehabilitation with physical therapy 3x per week @ 25 per visit. I can't do this and I don't know where else to go.
