Hi, I'm 5 ft 6 and almost 18 years old. I was sadly eating under 600 cals a day for almost a year and I eat mostly vegan/ fully vegetarian. I lost 40 pounds and then I found it hard to lose any more. I lost my period for the whole year and my hair started to fall out, I was told I needed to up my cals. Now it's summer and as soon as school let out I forgot everything I knew about dieting and let loose! I gained 25 pounds and my cloths are super tight. I feel awful, but I still in my eyes look slim. My period is back and I'm eating around 1500 a day. I'm not sure if I should lose more weight to get back to where I'm happy at (under 135) or maintain this 155 weight I have been experiencing. Anyone have any suggestions? Am I healthy now or can I make myself happy and loose 20 pounds?
