Gender Disappointment!! How to avoid "what are you having" question

So I found out three days ago that I am having my third boy. This is my last pregnancy and now that it is confirmed I will never have a daughter I do not want to tell anyone about the gender until delivery which is in January. I hate the pity eyes look and people telling me things I hate to listen to. How do I avoid people constantly asking me what is it that I am having. And those people include my sisters and my close friends. I just lied today that baby legs were closed so they were unable to see but I don't think I want to lie for too long. I'm miserable right now and the word "boy" makes me cry like a baby so I don't think I'm ready to talk about it. PS I know I should be happy my baby is healthy and all but I am not disappointed in the baby. I love him. I just need time to get over the loss of never having a daughter.
