I haven't signed on or been around here in a long time. I saw your post and had to sign on.
I went through an identical situation, 99% identical. I can only give you a few thoughts that may help. Firstly, stay focused on the present and don't look ahead too far as it will only drag you down and worry you more. Enjoy every single day. Secondly, be the "rock". No matter what happens or what your mind is telling you, never, ever flinch in front of your bride. Keep your chin up for her to see every day. It will help.
Stay strong, both of you
