New to this site and think it is pretty awesome!

Hey everyone! As my subject indicates, I am new to this site (and to be honest, to the whole sticking with a diet/exercise program thing as well). I really love the idea that this site lets me track my own progress, but what is even better for me, is the ability to see others and their struggles and progress. I am 28yrs old and started this journey at 258lbs (yikes, I know!). So far it has been really rewarding, yet really hard. I have a roommate and lots of very close friends who eat what they want, when they want. That can be a bit difficult at times. The worst part for me though, is the fact that none of them really ever want to work out with me or anything like that. I read so much stuff that says people who diet and exercise with friends keep with it better, but even my friends who work out a little seem to laugh at the idea of working out together whenever I suggest it. It is not the end of the world, and I still love them all to death; I just need to look for other forms of motivation to keep me going, and this site seems like it will be a really great one
