I have my surgery at the beginning of November, so this thread is really interesting for me. I think it's great that you are all talking about this, because there's nothing worse than feeling like you are alone in experiencing things a certain way.
I actually really struggled after getting a date for surgery, because all of my insecurities about my body suddenly became much more intense. I feel better now, but no one could understand why I was struggling.
Also, after my FFS I experienced very intense post operative depression, because my face either hurt or was numb, and I got a couple of infections. I was totally unprepared for it then so hopefully this time I will be able to recognise it for what it is.
I think it will be a case of time, to get past the pain and the constant maintenance. I hope you all feel more positive soon.
