I take care of my Father and Mother who become very verbal abusive with my kids and I.I took care of him round the clock last year he became healthy and i got sick.Just finished chemo and radiation and the stress they put in my life (because i live at the same house) is just too much.I just want to pack up and leave.I have a brother who is never there and a sister that lives in a bubble far away.They do not even call to ask how i am doing but just create problems.Should i just move then they will be in a nursing home in 1 month or less.
Time to pack up and move out with your children as that isn't a good environment for them. Once you find a new place, give your parents, your brother and sister notice that you are leaving because the stress is harming your health [don't say anything more]. And if your siblings try to get you to stay on just say "sorry, I just can't do that".
I don't know if this would help, but you might try researching online to see if there's a Gilda's Club near you, then contact them and ask if they know of any temporary housing you could get while you're looking for something more permanent.
Over a dozen years ago, I became aware that Ronald McDonald facilities housed families with a member who was undergoing treatment for cancer. I believe they were located near major cancer treatment facilities, and housed the parents and children while the stricken family member got treatment.
I don't know if McDonalds still provides that service, but it might be worth a try.
As I wrote earlier, research to see if there's a Gilda's Club near you; the camaraderie of other people in treatment will be very supportive for you.
Also check out the CURE magazine website. It's an excellent source of information on cancer, treatment, recovery, adaptation, etc.

Your oncologist or hospital social worker may also be able to identify home assistance for you once you find another place to live. My sister's oncologist suggested that, but my sister told her I would do the work!
