How can i grow taller?

I am really really really short. I don't know my actual height but when i compare myself to my other friends, i am quite short. I get picked on about it most of the time and now it's really starting to annoy me. Are there any foods that i can eat to make me grow or any exercises that i can do? I don't know whether it's in my genes or what as my other siblings are quite short and my mum is quite short apart from my dad and my brother. Any advice will do thanks.
