Beginning In December Of 2010, I Had Surgery, Chemo, And

Beginning in December of 2010, I had surgery, chemo, and radiation for breast cancer. Because the cancer in one breast was estrogen receptor positive, I have been on a hormone suppressant for five years. I had my last Faslodex (sp?) shot five weeks ago. Yesterday, during a meeting, I got unexpectedly emotional (feeling like I was going to cry) for no good reason. I did in fact cry after the meeting. Is this something I should expect as a result of discontinuing the hormone suppressant?
