I wonder if she's having an emotional breakdown?
I had one last winter, which is why it comes to mind so easily for me-so maybe not.
But, one of the issues I had-was a totally inability to handle any input regarding anyone else (including my one boyfriend who lives with us).
I don't know if that's the case or not-but if it is-what helped me was just having a couple months without anything to do with all of it. That allowed me to focus on myself and get my own head together.
(all the same players are in the picture as prior to my break-including the one whose behavior was "the straw that broke the camels back"-I just needed the break)
