I agree with discover. This is definitely an emergency situation. You need help right away. Like someone said before, reach out now and if the first person doesn't help, go to the next until you find someone who can help. If you tell us what country (and if in the US, a state) someone here might have suggestions on where you might receive it.

As discover mentioned, this might be time for you mom to be cared for by professionals. I know this can be difficult and cause guilt and terrible grief. so my heart goes out to you. Please take care and keep us posted.
