Sorry it's still so hard Hockey.

In any family there has to be give and take and accommodations made from all parties for all sorts of reasons. It sounds as if you're blaming yourself for everything and are thinking that your family will be better off without you. It doesn't work like that from my experience. If it's miserable for them with you there, it's going to be a hundred times more difficult and miserable without you there. Often when something devastating happens to a family member there seems to be a period of time when everyone rallies around, but then it stops. Do you have any extended family or really close friends nearby? Sometimes people don't know when we need help because we don't tell them.

Your daughter needs you in her life.
How on earth is she going to be happier without you.
