Hi Suzi,
First of all, I'm really sorry to hear that you find yourself in this position and hope you quickly find a solution.
As it happens I'll be doing GRS myself this summer too, miles away from home in Thaïland. I'll be going there alone and in my own case at least, I prefer it that way than having someone close to me involved.
This is all the easier to do as post-operative care is part of the package and this leads me to a question, does your surgeon provide no post-operative care in the recovery facility? If this is the case, I'd really suggest you rethink the choice of surgeon as in the first 10 - 14 days, you really want to have professionals looking after you and teaching you how to look after yourself.
If it's more about having company I'd just like to share my thoughts. I have already done two major surgeries since 2011, upper face FFS and lower face FFS, in both cases more than 7 hours of surgery leaving me battered, bruised and very tired for a good week afterwards.
In both cases, I went alone and just had a nurse come around once a day to help me with some of the after care, do a little shopping and keep me company for a while. Otherwise, I was initially just so tired that having someone else around would have been more of a hassle than a help and I was actually happy to be alone. I used Skype to stay in touch with my wife and a few friends and that was perfect for me. Basically I'll be doing the same thing in Bangkok but can also expect to meet other girls in the hotel once I've gotten over the initial recovery period.
In my mind, the very intimate nature of GRS, with huge symbolic content, adds an extra level of complexity and I just couldn't imagine one of my kids being with me for such surgery. When we transition we already make huge demands on our offspring who have to completely rethink the way the see their father, their male role model. Asking them to participate closely in a step like GRS sounds like a huge call to me and looking at it from a distance I think that you may yet come to see that your son's unavailabilty might well be a blessing in disguise regarding the quality of your relationship going forward.
So, getting back to the practical side of your present situation as you will obviously need post surgical assistance, what exactly does you surgeon provide and if you feel it is not enough, have you any means of getting some extra assistance even if it means paying for someone?
Hugs
Donna
