@desi09858 When I was your age, I went through a very dark period, also. Although my father tried to understand what was going on, he couldn't, and my mother was not available emotionally for me. But there was a friend of my mother, a mother of a classmate, who had all the support for me in the world. This lady took me under her wing and supported me, offering a safe haven to talk when/if I needed to. She took great care of me emotionally, and promised to never repeat anything I told her. Perhaps you have someone like that around you? Or an aunt/uncle/older cousin?

And like @lylii mentioned, writing down what is bothering you can be a great place to start!
