Most cities, counties, and states do have programs available for the elderly at little or no cost. Something like the Meals on Wheels program would be perfect.

Some churches even put an extra emphasis on assisting the elderly... and you don't always have to be a member of the church to get help. Do a google search of "Senior assistance programs" and type in your state. That should get you started. Get them set up with resources and then go finish your degree

And 25 isn't bad at all.. I'm 27 and haven't started college yet. :-p I was worried about graduating at 31 and someone told me "well, you will hit 31 no matter what.. would you rather do it with a degree, or without?"
