I was diagnosed on the 2nd September,and had my mastectomy on the 17th.it was my first time ever in a hospital,and I was pretty damm scared.anyway,the ladies on here reassured me that it was very doable,and do you know what?- it was.i came home after 3 days,and the pain was minimal.sleeping on my back was the hardest thing for me.im not sure how much harder it will be with a bilateral,but I'm sure it would have its own challenges.i wish you all the best,and I have found that reading what I can,and talking on this site,has really helped me.
