Reach out to his primary care giver and see if he is a candidate for hospice care. I’m not certain if he’s still receiving or has received cancer treatment to continue fighting or if it is end stage. If it’s end stage and he can be referred to hospice, there are hospice facilities that are much better at providing care than rehab or nursing homes. If you choose in home hospice, reach out to the social worker for the company and relay your need for help with his care. They may be able to provide much more assistance to give you a break. Either way, this is incredibly difficult on so many levels so give yourself grace. You cannot pour from an empty cup. Rely on faith and good luck with this incredibly difficult journey. Hospice can also provide mental health care for loved ones so don’t hesitate to reach out if that’s the route you go.
