Height 😒 Watch
You should be sleeping 8 hours tho and eating enough
You might be lucky and have more room to grow but height is largely dependent on your genes. So your siblings may have been given genes that mean they will be taller than you - that's just down to luck. It sounds like you aren't limited in terms of nutrients or anything... so if you may have to learn to deal with your height.
I stopped growing at about 14 and I remember being fairly average until the boys had their growth spurts. Even used to be taller than my boyfriend but now he obviously grew up and by the end of school I was pretty much on the small side compared to my peers. I'm over it now and take it in my stride
