'I've been scrutinised and some people say some really horrible things that I've had to delete or block. 'This made me feel even more self conscious about myself and my body, it put me under a lot of pressure to look perfect.' Sofia posted this picture to the social networking site explaining how she was not going to let people on Instagram get her down anymore . She continued: 'Only recently have I realised that every one has a different perfect. I may have never been perfect in other people's eyes or even my own but I have decided to be happy and positive. 'I know I will never be a stick skinny model girl and I'm accepting that fact. However, I know my body isn't as healthy as it could be so I'm going to change that. 'A friend recently told me that being healthy and dieting isn't about losing weight, living longer and looking better... it's about letting your body (and mind) be happy now and giving it a chance to explain what it needs (thanks @howtogreen).' Sofia concluded: 'Starting today I'm going to be as positive as I can about my life and myself. 'I have so much to be grateful for and I feel awful that I felt depressed around some amazing people because of the comments I got.'

'Any negativity will be turned into a positive thing... I'm going to start eating healthy eating. Not going for the full on vegan / gluten free / sugar free / carb free life but one where everything my body needs it will get. 'I am going to start going to the gym properly. However, exams and work are a priority right now so that might have to be put off. 'Hiking / dog walks are going to be a major part of my day.'
