Hi S&A. Have just been reading your sitch. What the others have said is really important to the DB process. 50 years is a long time..so many memories. There may be some depression going on with you as this would be a major trauma in your life. If you are really having trouble getting motivated you may need a trip to the Dr for some meds. Take any help that you can to get you through this, especially at the beginning. It does get easier, but its important to seek help if necessary. Keep GALing even though its really hard at times. You are lucky that you have many committments.. think of it as a blessing. Lean on others too if that helps. You have a wonderful family, they will support you and keep you occupied.
I would set the boundaries about your H visiting the house announced or unannounced as was recommended above. Try something different and monitor the progress. Good luck and look after yourself. Come here and vent..we all care.
