I'm new to the site

I was reading about this site and thought it would be useful, maybe a way to hold myself a little more accountable. I lost 50 pounds a couple of years ago when joining curves. Since then the curves has left and I don't go to the other gym. Seeing skinny people on a treadmill next to me running is really a motivator for me it makes me uncomfortable actually because I fear of what they are thinking about me next to them trying to loose this weight again. I would love to loose 100 pounds and really need to get my head back in the game again. I was very motivated the last time by my now husband and our wedding that was coming up. We have been married for 2 1/2 years and my weight has come back on. I like being comfortable with him dont get me wrong however we are talking about starting a family and would love to live long enough to enjoy them and retirement. : )
