Restarting. Need motivational friends!

Last time I was on here I managed to lose over 100lbs. Due to negligence on my part and a severe foot injury that took nearly an entire year to heal, I've gained all of it plus some back. I have quite a few medical issues, and my foot now has permanent pain. But I'm determined to get as close to what I was as I can. Problem is, I give up after a while. Whether the scale doesnt show me what I want or I start to crave something not good for me. I just...give up. I need friends who will motivate me to keep going and kick my butt if I need it! Please!!
