Hi Heidi, what you are feeling is totally normal, I cried uncontrollably on day 3, I thought I would never make it, but I did, and you can too! It's temporary, think of it that way, get different diet meals to change it up and honestly you will survive.
Try not to think about what you are giving up...I did the same thing after booking my consultation, I ate everything I could get my hands on and then Kim2Slim gave me some great advice. I shouldn't think that way, I can eat whatever I want after the surgery, but in moderation. There are foods that will not agree with us, and you adjust to living without them, we all have.
Remember, you are not alone, we have been through this, are going through this, or will be....and we are here to support you!!
YOU CAN DO THIS!!!
