Seems so to me. It seemsto happen when you focus on a figure like that so strongly for so long. It's why writers and actors have this sort of thing happen to them at times.
The main thing that separates DID from this sort of thing, is that one of the "qualifications" for DID is losing time, black outs, and some other disorderly elements. You may want to do some more in-depth research on the subject, but if you're creation is not doing anything to harm you, or you don't feel a drastic affect on your sense of self, I would not worry.
As far as an imaginary friend goes: They can't do much of anything without your hand in it. This doesn't sound quite scientific, but the best way to describe the difference is this: An imaginary friend is dead, while a "tulpa" is alive. My experience has been that the latter has a sense of liveliness and presence to it, where as an imaginary friend, in the most basic sense, is more like a doll. It's rather vague, but the human mind is weird, does weird things, and seems to defy hard definitions for what happens within its realm.
In any case, I wish you and yours well.
