I started becoming obsessed with my weight when I got back to school after the summer at the age of 15. I had been to America to visit a friend and without realising had shot up two dress sizes (UK12 to 16). I lost most of the weight within about 6 months - but realised that I wasn't satisfied with it. I wanted to lose more. I began purging at 18, during the summer after my first year of university. It started of slowly but within another 6 months I was purging anything that I ate. I would go through stages where I was so fed up with purging, that I would instead just not eat anything for days - only the occasional piece of chocolate or cheese to stop myself from feeling to feint. This has pretty much been my life since and I am now 21 and I really need to do something about it. I am not fat, but neither am I stick thin. I still want to lose a few kilos, but not like this. I find that having an eating disorder (especially bulimia as it is easy to hide from people) is incredibly lonely. Yes, I have plenty of friends and a family that love me - but no one knows about my bulimia. They have no idea how depressed I get in my own company. To them I am confident and outgoing. I hate living with this secret, and I want to get better so I can get on and live my life.
