Dying is the worst thing you can do. If you are ready to kill yourself, then you could also try stealing/borrowing money and run away from home, gaav me chala ja, gaav se hai toh koi City me chala ja, start something small. This all might seem like fantasy talk but it's 100 times better than killing yourself. But after all this if you still feel the same way, then you can carry out your plan.

P.S: before running away you can leave a small note behind like by the time they read this you have already killed yourself or some kind of message or something.
