yes, you need to discipline yourself by eating healthy and exercise.
You won't be able to predict how your body turns out, whatever happens happens, but darling don't be self conscious!!!! You're absolutely beautiful no matter what body type you have, you should feel gorgeous no matter what... be confident young one, because its the inside that counts
It is very likely that your hips will widen after puberty. I had the same problem when I was your age, and at 18 my hips are still widening. Btw broad shoulders are something to be proud of! You won't have to worry about your bra straps slipping off every 5 minutes. Don't be self conscious, 13 is a tough age, but everything will come together before you know it!
No way to tell if you will be built like your Mom or sister. Exercise is the best way to have the body your want and of course eating right. Nothing crazy just healthy in both food and exercise. You will be fine...Love your body no matter what...You the in control of it. If you like to bicycle...go an extra mile. Stay active...go for a hike. If we don't move and eat unhealthy chances are we will get chunky. Good luck!!!
