Hi, I'm sorry you're struggling right now. I know how hard it is to be surrounded by the foods you love but are unable to indulge. I'm a stay at home mom so throughout my process I've been preparing meals for my family while having to stick to my own "diet", and sometimes it was (and sometimes still is) hard, and very tempting. I think this is something most of us struggle(d) with at some point in this process. But, this surgery is only a tool and we have to make it work, as hard as it may be sometimes. The first few days on your pre-op diet will probably be the hardest because you are just starting to break the cycle that you have been in for so long. Just try to keep in mind that this is something you've been wanting for a long time and that the end result will be so worth it. Easier said than done, I know, but the liver shrinking diet is very important for you to have a safer surgery.
I'm only a couple of months out, myself, so I am by no means an expert, but I just wanted to let you know that I understand what you're going through right now and I hope as the days go by it gets easier for you. And, I'm sure you've heard someone say by now, that "after surgery, you won't wake up hungry." So just hang in there for these tough next few weeks and your surgery date will be here before you know it.
In the meantime, use the boards for support and maybe even mention to your family that you are struggling right now, and maybe they can choose some options that will be less tempting for you. Try having your "meal" or shake just before they start to prepare theirs so you will feel fuller and you may be less affected by the meal they're going to have. I really hope things ease up for you. Hang in there and stay strong! August 9th will be here before you know it!
