I've been preparing for the long journey to ortho surgery for the past 8 months (finding a great surgeon, planning with the orthodontist etc etc) and have finally decided to to take the plunge and go ahead with the whole thing. Problem is I don't really have my family on board (I'm 30, and having upper jaw advanced to correct underbite/crossbite and sliding genio on lower jaw to reduce chin).
My sister is, at best, dismissive (Oh you're so vain, what a waste of money etc etc), but will still support me, albeit with bemusement.
My mum, however is a different story. Knowing she'd be unhappy about me going through with it I took her along to an early orthodontic appointment as reassurance, but this has only served to entrench her thinking that I'm doing a terrible and dangerous thing to myself. I think she was hoping i'd "drop the whole silly idea", so when I sat her down last night and told her i'd decided to go through with it she was not pleased - all I got by way of reaction was a chilly "I see"

Now i'm wondering whether I should make further efforts to try and bring her on board or keep her at arms length through the whole thing. I'd really like to share all my thoughts with her through the process, but knowing her deep down hostility to it might mean that when I experience those inevitable what-am-I-doing? moments, she'll come straight in with "I told you it was wrong but you wouldn't listen", tears before the op etc etc which will be the last thing I need. As my partner and friends as supportive maybe I should just rely on them and keep discussions with my mum limited and basically "yes everythings fine mum".
Has anyone experienced this with their families? How would you guys handle it?
Thanks!
