The question of IShelpers came to discussion in another thread...
I've read quite a lot of this from here and there, but still I'm not quite sure that I understand this very well. Being dx DID.
I haven't found quite like that in my system, but yes I'm still in the early learning stage of my system, although I've read a lot about these things.
I have a kind of a ISH maybe. Her work is to always monitor any signs in any people that I relate with, about threaths of being abandoned. (My biggest fear is about being abandoned, has been all my life.)
So, in a way she helps. But I'm not sure if she could be called ISH, as what I've read about these things...
