Getting some help

So I found this website, my fitness pal.com, I am signed up to their site to help me with the last 80 lbs I have to lose. But I am now 200 lbs! 55 lbs gone now and there is a big  difference in everything. My attitude and energy and my overall feeling. No more negative feelings and all positive. Even my cloths. Most of all that, I am down to size 16 in my jeans now. I was in 22w and I am buying cloths in a large some xl but most large. I feel amazing but after I loose a few lbs I kinda slack and so nervous that I am going to get right back to where I started and I am not doing that.
Anyway back to exercising and feeling great :)
