Well, definitely set aside some time every day to unwind with The Snape Slash! Everyone needs a hobby, demmit! And I suppose there isn't much to be done about your mother until such time as she is judged mentally incompetent, the you can step in and maybe set her up in either a retirement village or a nursing home facility. Have you made any enquiries in her area or would you rather shift her to a local place when the time comes? If you had power of attorney you could speed that process up somewhat when it arises.
Hope you are doing better today, and I hope you have booked in to see the doc about those bruises.
