The 29-year-old 'Imitation Game' star said she used to read a lot about herself online till a few years back and the criticism over her looks used to affect her mentally, reported the Daily Mirror.
"Everything up to 25 I was pretty neurotic and taking everything far too seriously. I found it difficult to step back from it and I was taking it very personally.
"Partly because as an actor you don't want necessarily that thicker skin, and I couldn't figure how to be open emotionally and yet get a thick enough skin so that things didn't hurt," she said.
"I don't know if it was a chemical thing, a certain kind of realisation that it really didn't matter, and a sudden realisation of what you have control of and you don't.
"I don't Google myself, that was the problem before 25. Not that I did it all the time, but I certainly saw enough to say, 'Oh, you shouldn't look'. I mean, you don't need to look, it is not helpful," she said.
