2 torn ACL's and 1 job loss? What to do!?

I'm a 13 year old boy and I have 2 sisters. Last year one of my sister's tore her ACL. It was a low blow to our family because the surgery is really expensive. Now my mom just lost her job, and my other sister tore her ACL and some other knee thing. What can I do to make sure that nothing bad happens MONEY WISE other than try not to ask for stuff? Is there someone I can suggest to my parents? The first one tore while playing Ultimate frisbee, the other one tore during soccer. I live in Minneapolis.
