Hi Violet Bloom,
I really have no idea if this will help but it seems to be the only thing my mind comes up with.
Is it really a one or the other? My take is that it is not and here is why. Yes, if you have the surgery, that is no doubt a one way street. Not having the surgery is a two way street because you 'always' have the oppurtunity to go for it later. Will you be out the deposit? Yes, although what just may come out of that latter decision is just how real the sense of loss is. Maybe because of these strong feelings you have an excellent oppurtunity to check. If by giving up this 'one' chance, and the $, and you beyond any doubt realize it was a big mistake, that mistake can be a redo, the other cannot. Hope that helped. Dani
