Could I have affected my growth?

Probably not, it could be that it is your time to stop growing. I haven't grown at all since the beginning of 9th grade and I'm in the summer of my Junior year of high school. Everyone keeps telling me that I'll grow taller and hit at least 6 feet.. But I have a line that I drew at my house and at my dads house like 3 years ago and I'm still exactly the same. Other then that, if you wan't to grow taller just eat healthy. No soda or junkfood.
