Hello, i am 20 years old and standing at only 165 cm tall, and weighing 85 kilos. within the last 24 months i have put on roughly 20 kilos! This is without even changing my diet, lately i have started a bilion diets, losing interest within a few days, i am often tired, extremely pale and just not happy with my looks. I have a boyfriend, whom i have been with for the two years of the sudden weight gain, i am bigger than him and i am becoming very self concious.
