I am legally an adult for several years but I want to look like and be 12 to 14 year old boy. What's wrong with me? Is there a term for people like me?

I don't know if there's a specific term for this, but if it's something you're concerned about, the best person to talk to about it would be a therapist or other mental healthcare provider; they'd be the best person for helping you talk about this desire and your feelings around it.
