I understand your concern. We are doing home hospice with my mom. I have to say that we all thought it would be a lot quicker than it has. She was diagnosed in Sept. I moved in with her in Dec to take care of her and she got into the bed for good in Jan. She now needs 24 hour care and we are in end stage.
The reason I moved in is because mom did not want to die in a "facility". She has been a nurse for 30+ years and she just wants to die at home. This is a commitment that I made to her...to be there for her like she was there for me for all those years. There have been times when I have come close to "running out of gas". Here where I live, Hospice has respite care for home caregivers. Basically, hospice will admit the patient to a facility for a short-term stay in order to give the caregiver a respite or break. This may be an option in your area too and could likely give you another option that you may not have considered.
