Hi Kelly and Welcome. I've personally found alot of encouragement on this website, but the truth is, you'll probably find that you'll do best if you can find a friend or family member who wants to get that booty moving with you! If you know that every day your friend is waiting for you to take a walk or jog, or meet you at the gym, it'll be alot more motivating to get out there.
Set a small goal - for example, cut out sweets for the next 10 days, and check it as accomplished once you've done it.
Joining this website is a GREAT first step! YOU CAN DO IT! And you SHOULD do it now, when you're young, because you've already seen that you're heading down a road you don't want to go. It's easier to get back down to 135 from 190 than it will be from 290.
Write out your goals and share them with someone! Be accountable!
YEA KELLY!

you've made a GREAT FIRST STEP!
