Although, I have not had to deal with the issues of placing a parent into a nursing home, I almost did. It was horrible for me to even research the homes when my mother was critically ill last year. The guilt is something I think we all go through and you will need to feel it until you get passed it..
From others who have shared about their experiences, it usually is for the best. Their loved one generally receives proper loving care and the adult child still gets to supervise and be responsible in the loving way they chose to. It also gives you the opportunity to begin to sort out your own life once again.....to create a semblance of order...you are in my thoughts and prayers. If you care to place your mother's name in the healing circle...I would be very happy to do so.
Please let me know. Your mom is truly blessed to have a loving daughter as yourself caring for her. Blessings to you in all you are doing.
LOVE & LIGHT
