Hi. Be kind to yourself. Afterall, it sounds like you wouldn't have chosen surgery had you known this outcome. You have a lot of responsibilities and you don't have the physical resources right now to meet them. That's very stressful. Although my post-surgery experience has been different from yours, I struggled for years (and still do) with a chronic health issue that made work, parenting, and family life impossible. I felt a lot of anxiety, depression, and thought I'd have a nervous breakdown. You are doing all you can to get through minute by minute. Gradually, that will become getting through each half hour, then hour, morning, afternoon, day, week, etc until the worst parts of this are behind you.
In terms of nutrients, BariatricPal sells multi-vitamin patches. They may help you fill in what are missing through food.
I wish I had suggestions that would erase some of your struggles. Wishing you better health in the days ahead.
