A 'n A;
As a person with a tiny bit more life experience than you, I predict one of two things happening:
1) You will one day ditch the whole tulpa thing when you get older, get a job, get a girl/boy friend, get out of school, ie get a life and are no longer "bored".
1)a) You will divert your obvious creativity and imagination into writing stories, or producing some other art form as a healthier and more useful outlet. You will think of your tulpa time as when you were trying out new creative concepts, like an artist's blue period.
1)b) You will never mention your tulpa time to anyone. Ever. If someone brings it up you will change the subject. You will become a certified public accountant.
2) You will create many more tulpa. You will one day wake up in a strait jacket. I suggest you pick door number one.
