Help getting diabetic insulin pump

I've been diabetic for 19 years now. We've tried everything we can think of and still can't get this monster under control. I've seen several different doctors and they all suggest an insulin pump. Which is something I've been trying to get for at least 15 years. My insurance now will cover some of the cost. Only problem is I can't afford the left over cost. I will be forever in your debt if you could help me out. I'm not asking for a lot. Literally ANYTHING will help.
