Hi, Susan ~
First, let me assure you that your growing anxiety as Surgery Day approaches is completely normal. Although I'm sure you're in good (medical) hands and will do just fine, the thought of the inherent risks and the challenge facing the doctors who'll perform the surgery can be daunting. Of course, you'll be unconscious so your part is pretty easy!
I have to mention the fact that your worrying will not affect the outcome of the surgery one tiny bit. If it goes well, as I expect it will, the worry will have been all for nothing. Even if things don't go perfectly and/or you encounter some complications during or after the surgery, your previous worries will still have no effect on anything, except to have unnecessarily burdened yourself. Although you state that you're a 'high anxiety person' by nature, I believe we can all control our emotions to some extent. Basically, you have to
choose not to worry. Not easy or simple, I know. We all worry when facing a serious event such as your upcoming AN surgery. Many people posting here have gone through the AN removal operation
(including me) and come out quite well, even if a few problems emerged at some point. Nothing is insurmountable unless we allow it to become so.
I suggest you make a real attempt to banish the
'what-if's' from your consciousness as much as possible. That line of thinking is a dead end. Keep busy and try not to focus on your upcoming surgery all the time. Your kids will be fine. You should be out of the hospital within 5 days and although not up to much right away, within a few weeks you should be getting around O.K. Maybe sooner. As unique individuals, we all recover a bit differently. Most AN post-surgery patients can function on their own within two weeks. I'll bet you do even better!
I hope some of what I've offered here is helpful and of course, you'll be the thoughts and prayers of many people before, during and after your surgery. You have friends here, Susan.
