Have you told you mom that? I would expect she would cry that you think so little of her spending some of her best years with you. Ask HER if SHE regrets it now. I think you will be surprised to find out she counts her present problems as nothing compared to the chance to have raised you in the way she thought was best.
Yes, we have discussed it many times. We wish she had at least pursued something part-time or gained more education alongside my brother and I. True, she understands the choices she made and "regrets" no time spent with us - but wishes she had at least prepared to be on her own in her fifties with no education, no experience and failing health while competing with other entry-level workers.
Incidentally I am also a homeschool grad. So is my wife. I would rather live in a trailer and work the night shift so she could teach them than to send them off to day care of school or anything. No we don't have any kids yet but we will soon and it will be a huge pay cut when she comes home.
Good luck with this. Seriously. Your children will give you such indescribable joy. I never thought I would ever know such happiness as I do when I look into his bright eyes and my day cannot start until I see his little smile.
