Coming out in India

The core advice is to always hope for the best and prepare for the worst (ensure you have a plan B - financial independence, a safe place to go to, allies to call, etc in case things don’t go well), and remember that coming out to people usually gets easier after the first few times

An interview with a Queer, Indian, psychologist on Coming out
https://prajnyaforpeace.wordpress.com/2019/06/20/coming-out-in-india-questioning-western-psychological-models-of-gay-lesbian-and-bisexual-identity-development-with-dr-ketki-ranade/

Excerpt from one of the answers: In the Indian context, coming out is not so much an individualized identity achievement as implied in some of the Western psychological models. Because marriage is such an important social institution, we are conditioned to think of people in terms of whether they are single or married, with someone or alone. If you are alone, then anyway you are an ‘other’. When you are an other, what is the point of qualifying your otherness further by saying you are gay? Singlehood itself is non-normative. For single gay people, the question of coming out to parents is  also complicated by parents wanting to know things like: What does that mean? You are gay with whom? What is going to happen to your life?

And also coming out is not a one-time event but a lifelong process
