"15% mortality rate" = 85% survival rate.. Erin we all have to look at the BRIGHT side. When I went in for my Thymectomy my Dr. told me I would most likely not live through it so I went and saw all my family members did legal work and so on but inside I thought, if it is my time then I will go, if not then I will live. And live I did! Please, I beg of you to not dwell on that 15% but to embrace the 85%!
