I’m doing something wrong…

Before I started Wegovy 3 weeks ago, I drank coffee with Bulletproof creamer, 2 cups, and drank my Circular water all day. I can’t take lunch until about 2:00 or later and it’s a microwaved low calorie boxed lunch, and I can’t eat dinner due to my schedule until 8:00 or after. And it’s not big portions! Haven’t lost 1 single pound. And I do exercise with my waist spinner. I have back problems so I can’t walk long distances. What am I doing wrong??? I’m just crushed. I do have a highly stressful job, usually from 8:30 to around 7:00 pm. Do I need to move up to .5?
