Terk, I cannot tell you how sorry I am.
Reading your post just broke my heart. My Mom was my best friend also, and losing her seemed like the end of the world for me.
But you will soon realize that you NEVER really lose a good mother. She is always there, in everything you say and do. She will come to help you when you're in trouble, she will send help when you need it, she will always have a hand in her "baby's" life.
I saw the look of "understanding" in all who had lost their mother's before me when I was so shocked at how she remained with me. They did understand, and you will, too.
God bless you, honey.
Tell her to say "hello" to my Mom and Dad, too. I know she'll like them!
