Has anyone else experienced this?

Has anyone else experienced this. I wake up in the morning with a flat stomach and hours later I look like I’m five months pregnant. I have dealt with excessive bloating, weight gain, and extreme fatigue even after sleeping for eight hours. I’ve been in every diet and nothing works. I’m a pretty healthy eater and don’t eat a lot. Had anyone experienced the same symptoms and have similar looking photos? If so, have you been formally diagnosed with anything?
