As with the name of this site - Psych comes from the Greek word to mean "life" "soul" "spirit" "self" - so physical therapy is therapy to treat our physical selves and "psych(o)" therapy is just therapy to treat our inner self.

It is unfortunate that the term "psycho" has been adopted by some as a slang term - maybe psychotherapy would be better labelled as psyche therapy.

I can however understand how difficult it may be for you to engage in psycho therapy - particularly with your initial experience and the meaning this term has for you.
