So, two days ago my mother fell in the middle of the night in her memory care room and instead of notifying me, the medical staff there contacted my sister instead. I emailed the memory care director today cc'ing my sister on the email to ask her whether or not she updated the medical staff with the new designed representative (me). No response yet.

I also learned in having a conversation with my sister (unfortunately, until our mother passes away my sister and I have to stay in touch), that she and our brother have been going on spring break vacations together with their families for the past few years together. That news hurt because the two of them clearly want nothing to do with me. I maintain our mother's FB account (to keep in touch with her friends and update them) and this is how I learned that news.
