Emotional roller coaster

Just when you think you are about to get off this detour and return to normal life you realize that it's not all that straightforward. Physically I am getting there but I just realized that my emotions are still as raw as the skin on my chest after 25 zaps of radiation. This weekend I have a work Christmas function, an extended family Christmas party and my daughter's 21st birthday. I am looking forward to all of these events and will see many people for the first time since my diagnosis 7 months ago. So all should be good but for some reason I keep tearing up and am really worried that it might be a very emotional weekend. I don't want to ruin happy occasions for everyone so how do I pull myself together and concentrate on all the positives? Could it be the tamoxifen? Help! Deanne xxx
