I was in a relationship with a girl and after four years she says that she can't marry me against her parents wishes. My life has come to an end. What do I do?

Hey! I feel for you. I myself had a love marriage and it happened once that we kind of broke up and I know how it feels. I was completely heart-broken, and it seemed that my whole world has come to an end. I kept on moving with the daily chores and talking normally with my parents and relatives but I was broken. Firstly, I think you need to ask yourself that do you know your girl enough. Do you think she is just scared by the situation and let her have the hang of what is going on. Give her some time to analyse the situation and if you think that she is still not standing up for her love, then it is time to give up. I know it is going to be harsh but you have to move on. That is life, and sooner or later you got to accept it.
