I know just how you feel!i start my pre-op liquid diet tmrw so the past month I was going crazy,eating everything like It was my last meal!i was so scared,and still am,to let go of food after it being a huge part of my entire life.i didn't think I was going to have enough time to get all my favorite foods in before I started my liquid diet!after eating all day today and feeling like I was going to burst open I shared my concerns with my mom.what am I going to do without food?what if I miss it?what If I can't handle it?ect!but as amazing as food is,feeling healthier and happier I'm sure is a lot more amazing!stay strong and good luck,and just remember your not alone!im feeling the same way and I'm sure others are as well:)you got this!
