This is horrific and is caused by the pride of those who are too lazy to lift a finger. Just know that bitterness will only poison you from the inside out. Don't allow this to fester or it will make you like them. I have seen the effects of this in my own family and it ends in evil.
I'm sorry about the effect it's had on your family, these are hard things to bear.
I've started praying again last year, and generally trying to live according to the kinder values of Catholicism but it's a work in progress.
