Wow - congratulations on losing over 100 pounds. You should be very proud of yourself.
Of course you haven't "ruined everything" by gaining 10 pounds. We all get side-tracked now and again. But, now you need to tell yourself it's time to stop and get back on course. You can do this!!! Make a plan and then get up tomorrow and tell yourself that YOU CAN DO IT.
