Cindy...I'm so sorry for your loss. This disease robs each of us of our loved ones.
My MIL passed away just 2 days before this last Christmas. I was on my way to see my own Mom (who is in the 10th year at an Alz. facility...an hour away) when my husband called to tell me. She had lost a large amount of weight also...her little body just seemed to shut down...she weighed only a little more than 60 lbs. I feel so bad that no family member was there when she passed away...there are 3 sons and another DIL...and I had stayed quite a while with her the evening before...but only a compassionate caretaker was by her side.
Cindy...your MIL was very aware of your love for her...bless you, bless you for being there for her. I understand what you're saying about your FIL also. My FIL has also been in an Alz. facility...for almost 3 years now. He's a real challenge for the caretakers.....US too!
Those who gather here DO know the feelings you're going thru....most of us have been where you are and understand. I'm so glad you've shared this with us. Writing is excellent for you........and reading other's challenges is often helpful to others here. Sending prayers your way.......Pam
