Nicki,
I am truly sorry for the news you and Tom have received. I have not been through the surgery but others will be able to help you as you both have to take this next journey.
Tom could very well return to "so close to normal" that you won't really know the difference except for the strangest times. Even though it won't be the same, life will be very full of love, laughter and happiness. Your love for each other will grow in amazing ways and the things that seemed so unimportant in life will take on greater meaning. The things that used to bother you will soon fade away and you will have a new outlook that will be much better in many ways.
Grieve the old life. Go through all of the steps necessary to grieve...denial, anger, acceptance,etc. Then...move on to your new lives. If you need anything, you know how to contact me. I will be praying for Him to hold you both in His tender, loving, healing hands now and forever.
May He continue to bless you in many ways.
In His Love,
Ed
