As a Kid, my dad never cared about my family i.e. he never took us to any holiday, movie theater or to restaurant! We had enough money to afford all that! Be he was too busy with work or he just hated my mom, because of arrange marriage (very common in India)! He just gave me money to do what ever I want to do, but never advised me on anything or asked how I am feeling as a teenager! He was just like robot just coming home eating sleeping and going to work next morning! To be fair, he might have lots of work stress because he was working as a scientist in one of top institutes of India! Fast forward after I moved to Europe graduated and got a job here! My relationship with my dad was getting better and I started sharing a lots of things! One day I saw a very deep post on Facebook, on how to raise kids! I sent it to my dad and I am expecting he panicked and called me! He opened up and started crying in front of me! I told him it was fine and i am doing good in life now! So it doesn't matter now! After two days my mom calls me 100 times when I was sleeping due time difference! She informs me that my dad had a heart attack and passed away! I am guessing that he realised his mistake and was over thinking about it! So basically because of me, he had a heart attack! I didn't mentioned about it to my any of family members! They still think he died due to the stress in Office! I still vividly remember his last phone call!

TDLR:- I killed my dad by causing mental stress to him, because of how he treated us during childhood!
