I don't know you, but I don't think all the stuff you're saying about yourself is true. You help out your family, including your sick parents, children, and grandchildren. Would a worthless piece of garbage do that? I think not.

For example, my brother is seriously mentally ill and needs to be taken care of about 24/7. But I don't do anything for him. I live 1000 miles away and only go home for a week around Christmas. Even then, I avoid him as much as possible. Does that make me a worthless piece of garbage? If you think not, then you're not one either.
