Cancer and Shitty People

Jessica
SO I want to know if you guys think I'm overreacting... I was in remission for thyroid cancer (people can say what they will BUT it's STILL CANCER, and last time it started spreading within weeks of finding it) I found out yesterday that it's back. I just graduated college, so I am starting a new job next month AND moving to a new city next week. To say I'm stressed and overwhelmed is an understatement. I called my relatives to let them know the results of the biopsy and one of them had the nerve to COMPLAIN to me about basically EVERYTHING (moving, school, landlord issues), and kept interrupting me to talk about their own issues... I was already upset and didn't know how to respond to this, so I just got off the phone. I thought this was incredibly insensitive and weird, and didn't know how to react... am I overreacting? How would you respond?
