cubagirl I don't know if you have considered a breast reduction ( its certainly not for everyone) but it seems to me you would be a candidate on the NHS, though it depends on your local Trust.
I could go on gushing about how wonderful it is not to have the weight causing rib and upper back pain, no deep groves on shoulders, no more problems underneath the breasts, not having to pay a fortune for bras, not even having to wear one if you don't want to, the list goes on, and yes you do pass the pencil test, I still do even after seven years.
It is a big decision but hundreds on women do make it in the UK , either privately or on the NHS.
