Hi Emma,
Your post reminds me of exactly what I went through too. I am now 4 months post opp. I wanted to tell you something that helped me understand and relax about what was happening. My Doctor explained it to me this way. If you and I were both to cut our thumb on the same day, at the same time in the same way we would heal at different rates. You may heal faster or slower than me. This is the same concept. My stomach took a very long time to heal. EVERYTHING you describe I also went through and even ended up in the ER. Please be kind to your new little tummy. Lots of water, stick with things like jello, broth, protein drinks, etc. I know its counterintuitive and it can feel like your going to starve to death because you cant eat right now. I assure you that you are not and that you will be okay. Do what you can and keep your mind occupied elsewhere (trust me I understand your thinking about this alot I get it too). Pace yourself, be patient and kind to your body. Take warm showers, read, rest, sip and relax. Try tea, or try frozen protein drinks. Small amounts. Your simply not healing as quickly as you thought you might or as quickly as others. I am 4 months post opp and I still cant handle ALOT of foods, so for right now Im concentrating on the foods I can handle and the things I can control while my body heals. I completely understand what is happening to you and just want you to know its going to be okay.
