You will be fine, this is a wait and see game. You have done great to already have lost 30 pounds. Remember your body has to adjust to that and then you will start losing again.
I started off kinda the same way and since the weight loss has been alot slower but steady. I run into weeks where I dont loose anything and then I will start losing again. Just keep your chin up and it will happen for you.. Congratulations on what you have already accomplised!
