Hey Bella -
You've learned that weight LOSS is only part of the problem, and it is weight MAINTENANCE that'll be problematic. One of my favorite things about 3FC is that we have an active, supportive Maintainers forum, so when you're at your goal weight, you'll have support there in keeping it off for good.
Since you're pretty close to goal, you might also check out the Featherweights forum...for those with less to lose than others. Or just look around and find a spot or two (or ten!) where you fit, and keep posting.
Can't wait to see you around and hear more from you soon!
