Is it a complete NO for me in athletics or can i still do it?

you need serious discipline and dedication, be sure to properly stretch before and after any type of sport or you will hurt urself badly, i was lazy and didnt stretch properly, was a starting point guard for my basketball team, and pulled a bunch of muscles in my left leg, it was in constant pain and i couldnt move it or walk on it, always stretch properly, yea its boring but very important. but if you have to dont just practice at school, do it at home if u have to also. but dont wear urself out or over do it ull hurt urself. all you can do is put forth 100% effort every single time and hope you come out on top. only time will tell how far you will make it, just follow your dreams.
