Sir I'm A Girl Of 20. I Like To Eat

Sir I'm a girl of 20. I like to eat raw rice frequently. Even sometimes i can eat 1 kg raw rice. I'm addicted to the smell of petrol & kerosine. I want to give up these bad habbits. But i cant. I feel like dying if i stop these.
Please help me. What should i do? :'(
Can these harm my body or skin or teeth?
I use to brush twice a day.
