You got to live with that. In whatever you do, whatever you want to do. Never look at them. Ignore them and move on.
Stop worrying about what these haters would say/think about you and your work. Believe in yourself and step forward.
When you succeed, these haters will still be there. So don't even look at them. I am all for accepting positive and constructive criticism but cannot sympathize with haters.
For the largely successful Lorde Royals song there are almost a lakh of haters :) So you can expect more. So ignore and move on.
