I went through this a month ago. I know what you are going through. I knew him for 19 years. Idk what he went through in the final hours. He just got married a year ago. Everything from outside looked golden. I would have had any questions regarding my problem in life he always gave honest feedback. Nobody would give me suggestions about life like him. What broke me was when I went to his house after 3,4 days and his brother opened the door and said. "Yaar agaye iske.... Chala gaya vo bhai..." I have never cried and I don't usually cry. But I broke into tears... All I can say is. Pray that he is in a better place and start getting use to this void...
