What position am i for volleyball?

I have been told that I am a good middle Hitter, setter, Libero, and outside hitter. I am 5,4 1/2 and 13 yrs old. When I block over my whole hand gets over the net. I am really aggressive and never let a ball drop. I can jump pretty high (well at least i think i can. When i do my approach my hand is 7-8 ft high) my spikes are really hard to return since they're really hard and powerful but sometime don't go exactly where I want them to. I think I'm a middle hitter and my old coach told me so but other people (friend siblings and other coaches) have said otherwise Im in 7th grade and my 5th and 6th grade coaches both said I'm libero, My sisters and friends say Im a setter, my summer coach between 6th and 7th grade and some friends said Im a middle hitter and my 7th grade coach said Im either a middle hitter or an outside hitter. what am i? also what should I do to be a better middle hitter or setter if Im not them? thanks!
