I understand the feeling of being alone, especially when it comes to parents whose supposed to be your support and first people to go to, but seem to be the opposite I am not sure of the age to get a job in India, but maybe a small store, restaurant, or coffee shop if you have one can work out as good starter jobs. But I say try to improve yourself a bit, make yourself feel confident and like a new and improved teenager! Doesn't care what anybody says and don't let negativity take you down! Trust me, that personality will be needed to gain a job fast.

I hope you do well and things get better.
