Your are requested to describe hypothetically the symptoms of a psychological disorder from a first person scenario (as if they apply to you). Which means that you have to imagine that you actually have that disorder (without really having it, just by learning about it from the text) and you are explaining it to your therapist. Others have to try to guess what it is so you want to be clear and provide a few clues..
me: hello dr.
dr. hello dear. how are you today?
me: i am good. i just washed my hands twenty seven times so my day will be ok. i might have to wash them one more time just in case but i am really fine. it is easy for me to wash them. the only problem is i do not always find a sink…..
