Some Bosses are not nice. Do you work on the weekend too? Can you bring your Mom to your home and get her a nurse to be there when you are at work? it is the only way to do this, I am so sorry you are going through this hard time. We all do and it is never any fun. Are there no relatives to help you?
There is iHss that you can apply for to have someone come to the home as a caregiver and they are paid for by medicaide. I believe the link is www.iHss.com.
Prayer is the only way to calm your nerves God is present.
