What a lovely way to think of it - only halftime! It's in the second half that all of the good plays happen, anyway
Jennifer, you sound like you've gone into this in a good mental space. As long as you have a plan for eating and exercising, stick with it, don't give up, and don't be afraid to shake your body up once in awhile, you WILL see results. We had similar starting weights and similar goals - you can see my current stats in my signature - so you see it can be done!
Welcome, and don't be afraid to jump in!
