Just need a motivator , besides myself !

I've decided on working towards joining the navy. Now this has always been my dreams back when I was in high school but I got discouraged when I couldn't lose the last 15 lbs I needed to join . That was at least almost 4 years ago . Now it's back on my mind and I need to lose atleast 100lbs. I know that's alot but I'm determined to do this . I really would just like to have a girl I can text who also has weight loss goals but would like a motivator also . Kinda like a workout/diet pen pal, lol except no snail mail just texting would be fine . Any takerssss ???
