<human>: Can you provide a brief rundown of the text in within 3 sentences?

I am an average young adult. I have never been diagnosed with any mental health problem. I just feel like I need to get this off my chest and see what others think.

Basically every day, I play pretend. I'm not even involved in these fantasies. I have a whole elaborate story line that essentially follows one character and their group of friends. I feel an attachment toward these "people" and I always am replaying their story lines. They have extremely detailed lives and interactions. I constantly evolve their story lines, but overall one path is followed. The detail to my games of pretend is insane. Entire family trees with multiple generations have been planned out. These are deep, flawed characters. They feel multi-dimensional. The main person that I feel most attached to and usually follow is in someways the person I wish I could be. 

I will go and do this for around an hour or two. It happens while I listen to music and pace usually. Sometimes before I go to bed. I will also involve story lines from television shows and movies I enjoy. This has a huge therapeutic effect on me. It calms me down a lot. 

Regardless, I feel so strange about all of this. It is a huge secret for me, and something I am embarrassed by. I get extremely touchy when people bring up my habits that they have noticed. I have never told anyone and always do it when I am not being watched. I have complete control over this though. I always pick when I do it, and I have never started on my accord. I have no trouble separating it from my real life. Even though I associate with one character mainly, I don't think of it as an alter-ego.

What is wrong with me reddit? I want to stop having the urge to do this. It makes me feel like a little kid. I feel like I have a whole entire world existing within my head that I shouldn't. I get so embarrassed by the fact that I spend a lot of my time on child's play.
<bot>: I still play elaborate pretend. While I am in control of when and where it happens, I am still extremely is embarrassed. Is there something wrong with me?
