I agree. I don't think she is capable of turning off the self pity spotlight herself. Someone had to intervene. It might have something to do with doctor shopping too. Didn't she get fired by her doctor just before she went radio silent? Maybe the local croakers are communicating behind the scenes and sharing notes. One of them might have grown balls big enough to take the truth to mom. That would probably mean that mom had to grow a pair big enough to stand up to enabling earth daddy.
