Hi Tess! Congratulations on your success, you look fantastic! I love what you said about wanting to spend as much time as possible on this earth with your significant other.... that's how my boyfriend and I feel, we are in our 40s and only met three years ago, so we are on this journey to get healthy so we can have as much time together as we can. Good for you, starting this while you are young!
I'm glad you asked about books, I will be checking back to see what other people recommend! I've heard good things about Valerie Bertinelli's book "Losing It"... it's the next one on my list to read.
