are essential to everyone's well-being... mainly YOURS! It IS a contract of sorts...but one with lots of limits.
Also ask the hospice folks about what counseling is available to help your kids understand this all. Some have good resources, others not so good. I hope you find good ones!
My heart is with you on this one. It's not gonna be easy whatever the choices of what you do or don't do. But, the trying and caring are the more important things in the end. You also have to be very careful about preserving yourself! Sure, easier said than done? But essential to YOU!
Hugs and hope always!
