I very truly feel your pain. I was sleeved in 2009 and I did fantastic the first 6 years. I lost 149 lbs and 9 dress sizes. At first, I wasn't even exercising and the weight just melted away daily. When I got down to the weight limit that could not be exceeded on an elliptical machine that I borrowed from a sister, I started exercising on it. Eventually, I was using the elliptical for an hour, non-stop, 5 days a week.
Everything began to change in December 2014. My father passed away and he was the be all end all of existence for me. I am the youngest of 13 kids and was totally a daddy's girl. He was very ill already, but he ended up dying on my mom's birthday from a heart attack in his sleep. I was the first one to get to his house after my brother who was taking care of him called us all. When I got to my dad, his eyes were still open. My brother was dealing with the coroner and the police officer. I really freaked out and thought I'd better close his eyes before my other sisters or my nieces and nephews saw him. So I did. I closed my father's eyes. My heart broke in half right at that moment. I kinda lost my sh*t. My doc ended up putting me on Xanax and Ambien.
Fast forward a few months to April 2015, I ended up getting divorced. Then 15 months later in July 2016 my mother died. Her heart stopped, and during CPR administration, her ribs broke and one pierced her lung. It filled with fluid and because she'd had respiratory issues most of her life, they couldn't help her. She died after 3 agonizing days in the hospital. Then in 2017, I was transferred from one job post to another. They weren't even going to tell me until right before I showed up for work, I found out sooner by accident. I'd been at that post for 10 years. It was a retaliation from a supervisor who knew that I knew too much information about illegal activity that went on under his nose. Literally, every year something horrible was happening to me. The anxiety, depression, and meds led to me not giving a sh*t about what I ate and a lot of drinking. I was drinking every night. I wasn't exercising anymore. I was eating anything I wanted to eat. It was still very little food, because I had a lot of restriction. But I was eating every kind of junk food you can think of. I was eating at all hours of the day. I was grazing, as they call it. I could eat every 3 hours. And the alcohol was just straight shots of tequila. By 2022, I had regained most of my weight and gone back up 6 sizes.
You can lose weight again. You can detox from carbs. You can go back to protein shakes. This past May, I started dieting (on my own) because the doc wanted me to lose weight before he'd do the revision. I was drinking a protein shake for breakfast and for lunch, then I was eating a good, solid, very low carb (even zero carb) dinner. No alcohol. In 30 days, I lost 30 lbs. And this was before my surgery. It is absolutely possible, but you have to make the effort and you have to have the discipline. The first 3-4 days are tough as you detox, but then it just gets easier and easier. I wish you luck, friend.
