God forbid if my parents were fucked up, I'd be depressed too so obviously it's not your fault. Learn from their wrong doings and don't let their toxicity get to you. I'm sorry for saying this but your dad's behaviour is really shitty. Stay strong and the best thing you can do now is work on yourself and make the best of yourself.

Good friends can sometimes be like a family, a family that we can choose. I'm lucky to have one myself. I hope you have one too, bc it'll really help and he/she will become your rock and get you through tough times. Try r/makefriendsinindia or tinder. Most importantly, work hard and be kind and I'm telling you good things will happen. It's just true.

Hang in there buddy!
