Let's try this again! Need to lose 100 pounds

I have 100 pounds to lose. I used to be really fit and active and now no one believes that! Like I used to run 4 miles a day, spend 2 hours at the gym and play sports. I had no life, but I was sexy lol. Exercising was my escape from my crazy parents. When I left their house, I no longer needed to get out of the house to avoid drama so then eating became how I dealt with things. I'd like to change that. When I think of how much weight I have to lose and how long it's going to take I feel super discouraged. I need some friends that will help keep me accountable and motivated and I will do the same for you!
