How many calories did i get rid of purging?

okay. firstly i know i have a problem, so pleasee dont lecture me on that. i have anorexia with a binge-purge subtype. today i ate my first bite of chocolate in 3 years.. and couldnt stop. it tasted so amazing that i ended up cramming the whole 230 calories worth of it in my mouth. i swallowed it (!) and then straight away purged all of it up again. did i consume any calories from that? literally i purged it within seconds of eating it.. thanks for your answer. (i am gettting help for this by the way - from a proper therapist and nutritionist) x
