I understand how you feel about being consumed with thinking about this! I originally wasn't going to have surgery until March 22, but I was luckily able to move it up to Jan. 17 and if I hadn't, I probably would have literally gone crazy before then. As it is, I'm hardly sleeping and I'm on this site at all hours. I am so ready to have a new start that I want it yesterday. Now that my date is less than 2 weeks away, I am able to be a little calmer about it. Overall, I'd say it's worse than being a kid waiting for Christmas to come.
I wish I had good advice for you about your husband. Do you think it's the fact that he can't go or that he's worried about what else will change when your appearance changes? A lot of husbands/boyfriends seem to get insecure about their partners' weight loss, but maybe there is some way you can reassure him? Find out what his fears are and talk to him about why this is important to you and try to get him to understand that something so life-changing is bound to consume your thoughts? Luckily, my bf is more supportive and as the surgery date approaches, he has been asking more and more questions, so I am able to talk to him about it some, but I haven't told many people either, so this site is kind of my only outlet to talk about these feelings and thoughts I'm having about WLS.
I know it seems far away now, but your date will be here before you know it. In the meantime, maybe work on smoothing things over with your husband and do other things to help pass the time, like shop for Protein shakes and other things you'll need post-op. It's also a good idea to start an exercise regimen if you don't already have one. Best of luck to you!
