Harold we are so sorry for your situation. I'm glad to say that there are a lot of grants and assisatnce available to veterans. Some are available through the VA and a lot are also out there from private groups and non-profits, particularly in the area of housing.
Please stay up to date on offerings from the VA. You can also get some good information about what's available to help you in this article about grants for veterans. It covers both an overview what's offered by the VA and a number of nationwide programs from private groups. Be sure also to check out the paragraph about News in February 2016 -- new dental benefits have been added to the VA offerings -- hope they can help you!
