GRRRRRRRR I hate this feeling

Im down 82 lbs in a little less than 6 months but still feel like I'm not doing it right or fast enough. I did get to the gym tonight for the first time and feel good. I know I will be sticking with that because this time it felt different. I didn't hate it, I actually enjoyed it. I'm getting lazy and lax and I know it, I just need to figure out how to kick start my ass again, doing and eating the right things.
