I wanna make one, and use it for my emotions about someone, but I'm scared something bad would happen to me !

No. That's just superstition. Nothing actually happens.

Something terrible will happen to you if you do this. The voodoo doll will come alive in the middle of the night and eat your children. Then, it will call all of its voodoo doll friends and they will all eat you alive. And then, a giant meteor will fall on your house, obliterating all your remains.

Voodoo dolls are just a superstition, nothing bad will happen if you use one. Voodoo dolls and punching bags are great ways to get out your frustration.
