Answer:
Dear sis
Please take care of yourself! Eat healthy food, excercise regularly, and be sure to rest! Don't over do it, and tire yourself out, because I know how you are about that, and it is not right! This could affect you in the long run! You could get deadly and serious health problems if you keep up with this lifestyle! It is not healthy, and it is not okay. Change your ways sis, I'm worried about you! Hope to hear from you soon!
P.S send my love to mom and dad!
Sencerely, Alisha
