aye, there are no simple fixes - and i imagine your little one doesn't agree with you that it "needs to go". s/he may need to be heard.
i had a new one pop up - called self "little fox". drew a new mapping of the system and some pictures. can't tell if little fox is m or f. wants to leave home and mom but feels guilty. don't know if this is an ego state or an alter.

i am starting to be interested in hypnotherapy, too... and my t does that, but she must have decided that i'm not ready - she hasn't even brought it up since day one.
