Ohhh that makes more sense. Sorry I didn't see it!
I'm not really sure that Frances (is that her name? I don't know) is mentally ill. I don't think she is, but I do think she also needs to learn how to communicate with Farrah.
Sometimes, though, I think we attribute things to a mental illness or we assume the solution to a problem is therapy, when really it's not. Don't get me wrong, I'm a huge supporter of and believer in psychotherapy, but for people who are seeking attention, or believe the world revolves around them, sometimes therapy simply reinforces that belief, that they are the "victim" and there's a reason for the things that have happened to them that isn't them.
