Hi Vikki
It must be very hard not to have your Mum around to talk to for advice and guidance :hugbetter: If its any help I think your Mum was right in encouraging you to go for the surgery. I have a very good friend who had very large breasts (Im pretty sure she had a H cup size as well) and she spent years with back and shoulder problems. She also had two very deep 'dents' in her shoulders from the weight of the bra straps digging into her shoulders all through the years.
At the age of 45 she took the plunge and saved up for surgery. Despite her back problems she was never offered this surgery through the NHS (she lives in Northern Ireland).
Anyway, the surgery went absolutely fine. She was of course sore for the first week or two but each day that went by saw her feeling better and better. She got an infection in one of the breasts but it cleared up very quickly with appropriate anitbiotics. She says it was the best thing she has ever done and regrets that she didnt do it sooner. Its made a huge difference to her back problems as well as her ability to clothes shop

.
Of course she didnt have Lupus to contend with but then again thats a question best answered by your doctors anyway. Another idea might be to ask the consultant if he/she has any patients that might be willing to talk to you about their experiences of reduction surgery.
I also found this site that you might like to read. It gives personal accounts of breast surgery reduction. Its a US site but Im sure the experiences pretty much translate.
