Which words of the singer in "The Weary Blues" show his conclusion about life?

I think the conclusion of his life was the last line "He slept like a rock or a man that's dead. I think that singer was lonely. He lives by himself. He has a hard time trusting the people around him, but he longs to have someone with him. he considers himseld dead because he does not have a reason to live or people to share life with.
