Alice bot - does not seem to build to any thing
emacs doctor - a bit repetitive
samaritans - no history so they bail out a response based on the last mail only

other people as pretend shrinks - That is not what people normally do.
Aware (depression) group - no one to one interaction, all group work, and few bipolar, and the people change around a bit.
in contrast local ME (yuppie flue :) chronic lack of energy) group encourages one to one interaction, me bitter.
??? maybe some 3rd world therapist would put up with me emailing lots of junk in exchange for some cash...
