Hello Chris/Kris
The energy is not in your name, but in who you are. Your first priority is to yourself, choose which pleases you. Explain to those concerned as to why you wish to make the change. Those who love you, will love you by any name.
Here is something that I came across a long time ago that works for me. I hope it will for you too.
"So long as you are still worried about what others think of you, you are owned by them.
Only when you require no approval from outside yourself can you own yourself".
