Hello, I'm Diane. You're definitely not alone, I've got about 150 to lose, myself! You've gotten on the right track, which is great!
I'm 29, and I've been steadily putting on weight since middle school, so I understand. I've really had to work to change my mindset about food over the past six weeks. I've also had to come to terms with the fact that it doesn't happen overnight. Everyone I've met on here is awesome, and so supportive, so I hope we can help you succede!!
I freakin live on these boards, and I love having people to talk to about any aspect of our journey. By the way, if you're on Facebook, there's been a group started there called FitDayFriends.
