The way I look at it is, if they are upsetting you so much then you will find the money for a reduction somehow, it will be your number one priority, before clothes, holidays, meals out (after exante, lol!) etc etc. If you truely insist you cannot afford it then its not your number one priority, and isn't ruining your life. That probably sounds brutal, but thats how it was for me - I paid to go from a 30G to a C, but now I exercise so much I'm a B. Had I known then that I wouls not have a family I would have gone smaller, but I was only 21 and decided to go as small as the surgeon could get me without completely detatching the nipple, as this way I would still have a chance of breastfeeding.
What size wouls you like to be? I recently watched a documentary on such procedures on NHS and new guidelines suggest they should only operate on those who say 'get me as small as possible' rather than 'oh I'd like to be a D' etc. If that is how I had been assessed I would have been accepted - I would gladly have had them totally removed had that been offered!
