No, my life is not screwed up and I am not stressed. I make very good grades in school, and I have a very loving family and lots of friends.
I still constantly talk to my friend, and pretend that she is wherever I go.

Quite normal. I've been in love with a fictional character for a good few years now, who I wrote a blues song about when I thought he'd “die” in his programme. It could've become a hit!!
I’ve also had enormous crushes on lots of musicians, who I suppose have become something similar to me because a disability limits my life in a lot of ways (although I can talk fine) and I’ve listened to these people for ages and thought they're that good. So I write fantasy and have them shape-shifting or changing memories or something.
Close family/friends know about all this; they tell me I’m fine and just have a very vivid imagination which a lot of people don't –- and they should know. They're the type to notice if something was wrong or not. They even tell me to think of this fictional character when I’m anxious. As much as I wish he was real I know he isn't.
As long as you know your imaginary friend is just that you'll be fine.
