Gym Membership

My gym membership expired yesterday.  Now I have a decision to make.  It's not about leaving the gym, it's about the program.  I've been part of the Perfect Balance program for a year, and it's been great!  Life coaching, nutrition coaching, and and fitness plan that most of the time include one on one time with a trainer.  The thing is I lost 50 lbs pretty quickly, and I've kept it off, but I've been stuck since Sept.  I've been given all the tools I need, but do I have what it takes to continue on my own?  I'll save $700 a year by just going with the gym membership and letting the other things go.  I wish I know what to do!
