Maj,
That was an awesome eulogy - A mother in a Million there. Once 15 Years ago I had a mother like that - A truly awesome woman whom sets your mind on fire.
People will tell you the pain lessens, ignore them it doesn't, you just get used to the pain and that big hole in your heart where your mother used to be.
Do not be unhappy at her funeral, celebrate her life remember the goods things, her smile, her laughter, what made you smile about her.
And good Luck
