I can totally sympathise with what you are going through. I too had the same problem which knocked my confidence. i never told anybody about it, not even my parent. I eventaully couldn't take it anymore, told everything to my mum, found a great breast surgeon, and had my left breast reduced last May. I'm now a happy B cup, with only minimal scarring. I'd advise against getting the implant. That was offered to me, it's much more risky, and has to be replaced every 10 years. I had to get a loan to pay for the treatment, all in all cost be almost �4000, and i've just finished paying my loan, but it was worth every panny to be able to wear the tops I want without the worry of looking like freak
Good luck in whatever choice you make.
