How To Get Rid Of The Unwanted Hair From The Body?

I am a 15 year old girl and have too much hair. Before i shaved them i had a LOT on my arms and legs but thats not what im worried about anymore. I have hair in all the areas a 15 yr old boy would i believe. My back, my stomach, a li ttle on my chest, my feet, and my upper lip that i now pluck when i need to. What is wrong with me and how do i get rid of it. Its discusting. I know it might not seem like a huge deal but ive cried over this because i really do hate this so much and i dont know why its happening to me.! Am i going to grow as much as a real man does when im 30
