Aw, I am sorry you are having a hard time. You have a right to tell or not tell whoever you want. I wouldn't worry about people talking, you can't control people they will always talk. Only worry about you think. I have a told my department at work and a few work friends as well. I kind of wish I hadn't but who really cares. I am about to be hot, healthy and phenomenal so the haters can kick rocks. Good luck with your sleeve.
