I am so sorry. We are in a similar situation. Definitely contact his VA doc, and explain what is going on. Now, that help will be ONLY for your Dad. Call their county Agency on Aging. They can point you in the direction of additional help, and check what is going on in the home. Make sure you tell them that your parents have NO FAMILY SUPPORT IN STATE. The Agency on aging will suggest things like meals on wheels, and social workers to go out and check on them.

Also contact their personal family doctor and let them know what is going on. They can also send a social worker out, and check what assistance they might need.

( Been here, done this)
