I am so sick of being 163cm and looking at my perfect 5′9" model like friends chins and shoulders. I eat a lot of food, lots of protein, carbohydrate and calcium. I am a tad underweight, but thats how I am naturally, I haven’t grown in a year either. My father is tall but my mum is short. A lot of my cousins are really tall, were talking 6′5". My brother is 6′4". I hear that you have to be in a deep sleep at the time 11pm-2am at night bcuz thats when you grow, it’s a bit hard for me when I get into bed at 9pm and lay there for hours as I find it impossible to go to sleep. I usually doze off around midnight. I’ve been doing stretches for a year and increased my calcium and protein, but it’s not working. I don’t really want to take any of them hormones or anything, should I talk to my doctor?
