This isn't a new diagnosis. I've been sick for quite a few years. It has been documented. My family has let me take care of my father the last 2 years. I cannot do it anymore. My father is not getting cared for like he should because I cannot take care of myself sometimes. Sometimes I do barely enough to take care of myself. I've been hospitalized twice last year for wanting to hurt myself. Family did nothing. Before this gets any more out of hand I need to know my next steps on what to do in the situation.
What is your housing situation? Do you live with your father in his home, or does he live with you in yours?
Are you employed, or on disability, or does your father or family support you financially in exchange for taking care of your dad?
Call Adult Protective Services first thing tomorrow (Monday) morning and tell them that you cannot do this any longer, that you and your father are both at risk and unsafe, that your family refuses to provide assistance for either of you, and that it is an emergency.
Call 988 now if you need to. And keep us posted. We care and want to help you.
We can know nothing about your diagnosis or prognosis, or even if you are currently being paid to care for your elder, or if you are on disability.
If your doctor cannot guide you to social workers to form a plan for exit from this situation into one where you are in group home or small efficiency apartment of your own, then I would call APS and tell them you are incapable of going on giving sub-minimal care, and that you yourself need help and guidance for yourself.
Inform family this is the route you will now be taking.
