I hope things go well with your mother and heartily agree with the suggestion to intercept your mother's junk mail if need be. For one thing, it's a serious fire hazard and likely won't be tolerated. For another, there's no need to add to your mother's stress if she truly can't manage the paper. Don't feel guilty: whatever you do to keep your mother safe is a good thing. My own MIL is mentally ill; we had a terrible time getting guardianship over her and getting her settled into a home, but in the long run it was worth it. Her money is protected and she is safe.
