The last I saw the OP posted a long post finally saying how she really felt
& admonishing everyone who disagreed with her. Her extremely controlling Mom is the problem. Her brother, BF, & she are the innocent victims. Her horrible Mom went as far as to buy a vacation, lake house near her brother & close to land her boyfriend had bought. The usual suspects totally understood how horrible it is to have a Mom who financially & emotionally supports you, wants to be near you & is a rock in times of need.
The obvious thing to do is tell Mom she's out & not worry about her feelings. Others started asking who the OP really is & questioned the revised story. That's about all I read recently in a nutshell. Sorry, I had to take a break to watch college basketball.
I missed the part where the OP was a surgeon. Others need to fill us in on everything after that.
