Help for Medical Bills

I have a family pet Labrador that has a cancer on his foot and needs to be removed, my wife and I are disabled and retired on SS and a small retirement from a company I worked for we both need major dental work I go to the VA Hopital for my care, but my teeth problems have to be service connected in order for them to work on them, my wife has similar problems and I would like to get hers fixed so I could see her smile again, we have been married 48 years and I miss that old smile of hers. We are both on oxygen usage and have other medical problems that are genrally taken care of so far, she has Medicare and I have the VA so we are taken care of so so. We have never been able to get life insurance so I worry about that expence for when that time comes. It is very depressing to live like we do sometimes, but we get by. We have had an extrordinary expence for repairs this past year, mechanical problems with vehicle, our well had to replaced with a new pump, our refrigerator is on the brink and we have had to replace a new water heater, our air conditioner went out last year, it just seems like it all comes at once, its just like us getting older, it breaks down eventually. We have no family around anymore, the children are always too busy to help out with anything that relates to work for them. They are not in a position to help us financially, I would feel better for them just to give us a visit or a hug from time to time. The children of today are in it for themselves and only themselves these days. I am so embarassed to ask for help like this, I have never done this before, I have alays figured out a way to do things by myself, I have been on my own and worked since I was a young boy, I am now 70 and can't get out and move like I used to. We would just like to live with a little less worry before we go, and even be able to enjoy the sun rising for the day for awhile. That is all we ask for...Thanks
