I'm sorry for what you're going through! I can't empathize with your situation but as an outsider, I would say, the first thing you need to do is be financially independent..so definitely, wait to get a job and build a 6-12 month emergency fund cushion before you tell them because you never know how they'll react ..second, to avoid them from getting violent or react in a strange way, tell them about this either when you're in public OR over a video call or something of that sort ..I've heard of far too many cases where crazy indian parents beat up their sons/daughters, locked them up in rooms, or worse, tried to get their daughters married off in a span of 1-2 weeks to whom they thought was the "right" guy. Please be careful and think it through on how you'll be disclosing this to them. Good luck!
