Being criticised and criticise is a part and parcel of a scientist/ researcher life.
When I was starting my PhD studies I was warned by my Friend that I would be criticised very often. He said also very important thing – “remember that they criticise your work, ideas, papers, research etc., not you as a person. And treat this criticism as good advices of more experienced people, you can agree with that or not, but there is no need to treat it as a personal criticism.”
And this advice was crucial for my profession development
