Actually, that was fairly entertaining. If I were to provide some constructive criticism, I would say it's a little drawn out. I also would've found it more humorous if the doctor was more ignorant of the ninja world and its workings, i.e. she shouldn't know what the sharingan is. Another random detail is that your doctor seems to not know basic psych. or much about medicine. You might want to do some background research for a more grounded work.
Additionally, as I almost always say to writers of fan fics, it wouldn't hurt to have someone proofread your work to catch grammatical mistakes. You have a few.
Regardless, this is one of the better fan fics I've read. Good work.
