zi am 92 years and last week I went for my injection with Eyelea in my left eye

As soon as I got there I was told that the charitable company who was paying for my co-payment $330.30 no longer would pay because they ran out of money. I called my insurance company United healthcare and they told me that they help (90) diseases but NOT eyes, ears or teeth. So now my doctor told me he could inject me with Avastin which is cheaper but not FDA approved. This was originally used as a cancer drug. They have had a lot of poblems. He said that I was doing well with Eyelea and he also suggested a cheaper (not that cheap) Lucentis. I am looking for a charity company who would pay for my copay. My cap is 2400.00 dollars so as soon as the 2400.00 is paid the rest is free. I have not slept since I was told. Monday I am going to continue to try and find someone. Please help
