(((((((((((((Susierose)))))))))) I have never heard of anything like this nor have I had anything like that happen, but I don't know whether or not your friend has DID or any type of DD. Whether or not she does, in my opinion, it does sound like she has some mental illness going on.

There are reasons people decide to show various symptoms of different illnesses while not actually having them (if that is the case) and I do often think that is a mental illness in itself. I'm so sorry it made you feel uncomfortable. I imagine she doesn't realize how invalidating or uncomfortable that might make others. I think you were wise to block her from your facebook to cut down on the stress. Good self care. Perhaps you could ask your T about it as well so you can work through those feelings?

Take gentle care. We care about you.
