It is my first time in a weightloss forum, so please excuse me in advance if I look a bit awkward

My name is Inès, and I'm 18 years old.
I'm 173 cm tall.
In February 201, my weight was 70kg, and I was quite desperate to be thin, I then started a diet, which worked quite well.
In June 2011, I managed to be 55 kg. I kept this weight until February 2012. But then I had go to the hospital for a few days (which was absolutely not linked to the weight loss ^^), and ever since I went out of the hospital, I started gaining weight again, and I've completely lost my motivation.
I am now 62kg, and very unhappy with myself, that's why I joined this forum, hoping I could find support here !
I'm starting dieting today and my goal weight is 52kg !
Thanks everyone for reading :^)
