Credit Union Withdrawal from elderly woman's account made by in-law

Thank you
 
"...while she was in the home I was working overseas for 3 yrs "

Thats the nub of it in a nutshell.

You are abroad, other family members have to manage your mother's affairs for three years as she becomes increasingly unwell, then you sail in throwing shapes and demanding receipts.

Not surprised they've taken offence.
 
Yes that true
 
Yes that true
In the three years did you not wonder who was paying the nursing home the extras or the costs of looking after an empty house and dealing with the administration of your mothers affairs. Did you never ask.
 
And to give you the benefit of the doubt, I wonder if you feel bad about the fact that you were away for the last years of your Mother's life?

And that sadness has manifested itself in anger against other family members?

Maybe its time to forgive yourself & mend fences, we only get one life.
