Welcome @Sweetpetal,
There is nothing that prepares you for that earthshaking diagnosis. The fear that surfaces at the start is indescribable. No body can quite understand unless they have felt it. I remember each morning waking up hoping it had all been a horrible dream, unfortunately not.
No point in blaming yourself, there is no room in this process for guilt. Distraction is definitely the best method. I ran myself ragged those first few weeks (in between bouts of tears) just to keep my mind from turning to total mush. Once the ball gets rolling you will feel a little more in control and settle into a bit of a routing.
It will be ok, you will get it done and we will be right there beside you every step of the way if you like.
