Looking for support and like minded people

I have been using MFP for over 2 months now and I don't really have any friends on here that are doing the things I am to better my life. I started at 280lbs and I have a goal to reach 180lbs. I am currently down 42lbs so I have a long road ahead of me. I started barely being able to work out for 20 minutes and now I am putting in some serious cardio workouts. I wouldn't call myself a highly motivated person more of a dedicated person once I commit to something. I am currently in a weight loss challenge at work and once that ends I fear that I will fall backwards. So long story short I need people that want to motivate each other to be the best possible versions of us. Sorry for the book! Lets lose some weight!!
