bone age - 11-12 years old, (but I'm 17)

(Yes, it's me again.) But since I was very worried about my height, I decided to have an X-ray. I always suspected that I might have dwarfism. My bone age is so far behind my real age, I'm literally stuck in a child's body. But it's so frustrating, I really don't understand how this is even possible.

My parents are actually very short (father is 5'4 and mother is 5'1), but in that case I would have been at least 4'10 or 4'11. But my current height is 4'8,but my current height is 4'8, so but my current height is 4'8. Literally hell.

Has anyone had a similar situation?
