Hi @T0mmy
It's a tough one. I had a bilateral mastectomy with no reconstruction and was a size 26 at the time. I went with humour as a way to cope and referred to myself as looking like E.T. All belly, no boobs but still cute as heck :p I also try and remind myself that there's a lot of fella's out there with figures just like mine and they don't seem to feel the slightest bit self conscious about it! I promise though...I will not be popping on a pair of budgie smugglers and going to the beach :D
Another way of thinking about it was that the effing thing had a crack at killing me and there was no way I was keeping something in my life that did that! Good riddance to the rotten thing!
Anyway, there's all sorts of ways of dealing with this (and they can change hourly, daily, weekly) and you'll do it your own way and that'll work for you. Don't think twice about seeing a professional for some help talking it through. It can be incredibly cathartic to talk through what you're feeling with someone who has no skin in the game. If you're not already aware, your GP can do a "Mental Health Care Plan" for you which will subsidise about 5 trips to a mental health professional.
All the best xo
