Magical Gem

So this is a gem that has five powers in. The powers are nature, water, fire, air, lightning. You found the gem when you were walking in the forest and you decided to pick it up, when you picked it up the powers started to manifest in you. You start to lose control of the powers but then you get the hang out it. But you don’t want anyone to know. In school you were losing control of it and your friends saw you and they were starting to be suspicious about you. Some day they will ask what’s happening because people are not supposed to have powers like yours. What will you do? Will you get the guts to tell them? Or will you keep it a secret? Anything works. Good luck!
