I have very little money for long term care giving for my husband and I. Will I qualify for Medicaid?

I have very little money for long term care giving. About $30,000. My husband has Alzheimer's. I am prepared to care for him as long as I can, but he is healthy otherwise. When and if he becomes violent or really unable to care for himself I will have to put him in a home. He is bigger than me and I would not be able to lift him. So I am imagining that I will qualify for Medicaid early on after he goes into a long term care facility. I own my own house and right now my biggest problem is paying the taxes every year! I know they can not throw me out of my house. They have to let me live here. And I also assumed that my house would be taken after I die. Bit I have a life insurance policy on Bill that I was counting for to take care of me in my old age. I recently read that they can take that too for services rendered. Is that really true? I was thinking that I will need that money to take care of myself at the end of my life. If I don't have that life insurance which I have been counting on, I will have nothing but Social Security to live on. And that is not enough. Can anyone enlighten me about this situation. I have a lawyer but I think he is just after as much money as he can take and not looking out for me!
