I really don't know what is the best way to go on this question. It hurts to heal but where do you draw a line?

Just ask her if she needs support from those people that she feels comfortable with on the forum & can talk to them off the forum then maybe that is a better way to go at the moment. She may also think that if she isn't on the forum her friends will not be there to support her, sort of out of sight out of mind. I don't know, I'm just guessing.

I think you are right that maybe she just needs a break from here at the moment.
