I'm very very happy for my hardships and misfortunes: they build character and make you a better person. Even if I think it's something you have to carry with you, it's definitely something that makes you more empathic towards other people, makes you understand people and relationships so much better.
When I was a kid, I had a period in my life when I was eight or nine when I was so scared of dying that I wouldn't go out of our house for a whole year. I refused to step out of the door because I thought something would happen. I had all these compulsive thoughts or whatever, and my head was really messed up.
