so...are you off cycle? is this your 17th month as a PGY-1?
if you can't progress to the next level (and if they have given you 5 months to progress, they have been pretty generous to get you to the point), then what do you expect to happen? I seriously doubt that its about just 1 person not thinking you are unable to progress...this would have gone to your RPEC and the decision to let you go due to the lack of progression would have m/l been a committee one.
If you have the support of your PD, then try to find another spot somewhere, but you probably need to sit down and do some significant introspection to see if this truly is the path for you.
Medical knowledge alone can be taught, professionalism/addiction issues can be addressed, but if you can't take medical knowledge and integrate it with clinical actions to practice medicine (or guide others on your team), then clinical medicine may not be for you.
