Meeting the surgeon on Monday

I am meeting my surgeon on Monday the 29th. I am so nervous. I am supposed to lose 7-10 lbs by then to get my surgery date...but, even with the diet and exercise, the reason I'm getting WLS is because I cannot lose it on my own- I've tried everything. I'm so nervous that I haven't lost anything and it will postpone my surgery even later, mainly because i cannot get my psych evaluation until 9/20. (which is a total bummer). I understand that the most I'll have to wait for my surgery date is after my psych evaluation, but that's okay. I hope everything goes well. It's driving me bonkers.
