My 83-year-old mother lives at home, has a kidney transplant and is diabetic. How can I get financial government assistance for her?

I'm assuming she is on Medicaid. If not, you may want to look into it (unless she has a good amount of money). You can go to your state Web site and look under something like "aging services." There you should find contacts and many links to support. Find someone to ask specifically what can be done given your mother's specific needs. Most financial aid, even if it is federally funded, is state or county administered. I wish we had one place to find out all this information, but much depends on where you live.
Good luck,
Carol
