Welcome back to Sparkpeople. You are among people on the best support site anywhere as far as I'm concerned. Feel free to sparkmail me if you need someone to talk to. I am online several times a day, every day.
Take it one step at a time, one day at a time. Make your goals small to start with, then add new goals as you start to grow.
I will send you a sparkmail with a link to a team I have found really helpful for weight loss. Their discussion thread "one pound at a time" sounds like it may be something you would enjoy. I know I do. They have been very supportive.
