YES stop panicking
I think many RNYers will back me up when I say it's so common it'd be unusual if you didn't hit a stall around this point.
Don't worry, your body is being made
to burn its fat and all sorts of chemical and hormonal reactions are taking place.
Unless you can defy the laws of physics, you are still burning fat - it's just not showing on the scales - it could be water retention (from hormones, salt in food, exercise.....loads of reasons!), it could be changes in muscle or whatever.
Just think - if you are not eating enough to provide your body with energy it HAS to burn your fat to keep you alive, breathing and moving.
I know what you mean about wanting to see results after all you've put yourself through, I felt the same.
Just relax a bit - look after your water, then your protien, exercise as much as is comfortable for you and DON'T try to stuff youself - it will only hurt.
The pounds will start to drop away soon as long as you stick with the plan.
It sounds like you're doing fine - especially if you've got the energy for daily walks.
