Hi,
I am so very sorry for your loss. I can't imagine how shocking this has to be. I pray that somehow you can find a bit of peace to be able to mourn her passing. I know you are looking for legal help, but try to get past the painful loss first maybe? You have time for the legal stuff.
As a caregiver, I sincerely hope you are not in any way blaming yourself for this. Just a thought as I know how hard on ourselves we can be. We can't control the works of others, only the love and care we give.
I pray that the happy memories will help you through the future.
Blessings,
Kathy
