Jen,
YOU are the center of your health and any decisions you want to make should not be of anyone else's concern. Most people that know me expected me to call them when I wanted to talk or tell them anything and generally everybody left me alone, unless I asked otherwise. The key to health and recovery from treatment is to minimize stress in your life. If this means barricading yourself in your bedroom, then so be it. If they try to turn your life into their agenda, tune it out.
This is one time in life that I learned I could communicate proactively and everybody listened! I did not want a lot of extra people hanging out and I tried hard to still fix dinner every night for the family. Unfortunately, for them, when the taste buds went, we all learned (quickly) that I cook from taste, not recipe!
