If you are a 130 pound 5' 1 13-year-old is it okay to lose 40 pounds?

ok well that's a little overdoing it don't you think? i think you should just eat less junk and maybe join a sports team, or dance, maybe yoga! that's what i do, ok i weigh 78 punds and i am 13 years old!! only because i get huge adrenaline rushes!! :) but just try it and i just think that you should do what you want, nobody's perfect, so just be yourself! :) XP
