Hey VikingGirl!
If you're overwhelmed by the big number, why not set yourself mini goals? Is 10 lbs less overwhelming?
Let 10 lbs (or even 5!) be your first mini-goal. Work toward that. You can worry about the rest, in small chunks like that, when you get there.
This slight mental shift can make a BIG difference in the "overwhelming" factor. As someone who was staring down 130 lbs, I definitely understand the way you're feeling!
Look around here, settle in, keep posting, and stick around. You'll be hitting that mini-goal (and others) in no time.
