I agree with Ash that it obviously isn't nice getting comments like that left on her videos, but her response was a bit ridiculous IMO! Essentially saying that its comments like that, that have made her gain weight... em no, you can't put your own personal weight gain on to someone else.
Ash - I absolutely can appreciate that it can't be nice to read tit like that about yourself, but you've got influence over your own body and mind and I think its quite manipulative to say that someone else's actions have caused you to do something. You're a big girl and only YOU have control and responsibility for your own actions, not anyone else, not even the trolls.
