Welcome to our wonderful community forum!
As you fade, ensure that you maintain your dignity, poise and grace.
Be the same guy as you have always been. Don't play into the cliche of what an inactive person becomes.
Be happy, be warm and friendly. But do not live under the illusion that all your "friends" will retain the same warmth toward you, or be in touch with you as much. As you fade out of their witness circle, you will be slowly ignored, then forgotten. Then the rumours will start that will malign your name and character.
I don't say any of those things to discourage you or to be harsh. But being aware of the reality will equip you to handle the inevitable.
Most of all as it has been well said here on the forum : THE BEST REVENGE (or answer) IS TO LIVE A HAPPY AND SUCCESSFUL LIFE.
