Actor Hrithik Roshan has opened up about his childhood and said that his 'school days were very painful'. Recently, Hrithik said that he had a 'bad stammer' and was very shy when he was young. Hrithik starred as a child in several movies and made his Bollywood debut with the hit Kaho Naa Pyaar Hai. As quoted by Indian Express, Hrithik said, “I have sometimes felt that life is very unfair. In school, I had such a bad stammer that I couldn’t speak. I never had any friends. School days were very painful…on top of that, doctors told me that I couldn’t become an actor. There were problems with my spine, doctors said ‘you cannot dance’. I was so broken, that I would wake up for months, and would think it is a dream, a lucid dream. It was so heartbreaking and relive that feeling of knowing that I could not become an actor… I am disabled. So it was very traumatising.” “Now when I look back, I thank god for giving me the problem where I could learn how to be strong, I learnt perseverance,” he added.
