I am truly sorry to hear about the passing of your mother. It is a coincidence that my husband died on the same day. I can't really say that I know how you feel, because death affects all in different ways. However, I do know that losing a loved one in death is a very emotionally painful experience.
I have chosen to hold onto the fond memories that we shared. Then I consider myself fortunate to have studied God's Word the Bble. In doing so I have found the real condition of the dead as well as the hope for the dead. If you would be interested in knowing more I will be glad to share.
In the meantime you have my sincere condolences.
