Seeker, I'm so sorry this has happened! Please know that although she is very ill, your mother, unless the cancer has gone to her brain, is still responsible for her actions.

You can't be with her and awake 24/7. Maybe a gentle restrain will be needed when she gets over this.

"I've done all I could for this evening."

Yes! You have! Now do some serious self-care while you have the chance. Tell Guilt to take a hike. You don't have time for it.

Take care, friend.
