well terumoto its practicaly impossible to not have a personality. now whether its original or not is one thing but just by reading what u said i can say all your seperate personalities aside you very much have a real one. i can say your "playful" and "experimental" or your "insecure" and "fearful" since you could have all these seperate personalities to make you feel more important and ta re-assure yourself that your somebody in this world. or you could have them all as a form of protection from people really knowing you. another thing i can say bout you is that "your good at acting" all traits describing a personality and thats true about you.
