New to this site

Not too sure if this is the site for me, i'm having a difficult time finding a site I fit into....i'm a p/t fitness trainer, and a can post mail carrier, who is taking my career down the fit model track, i've had quite a few jobs, but I keep getting the same feedback, call us when you take off a good 4-6 pounds. I know this may sound ridiculous to people who are trying to lose a significant amount of weight, but 4-6 pounds for me is like asking me to lose 100. I eat extremely healthy, 6 meals a day, no sugar, no bad carbs, high protein. I allow myself one oatmeal cookie per week, I exercise 6 days a week 2-3hours a day, sunday are my rest days, but lately i've been doing cardio to burn a few extra hundred calories. I incorporate, spinning, hiit training, weighlifting, sprints, plyo's...I do it all. My body doesn't want to shed the weight, but being a single mom of 6 kids I need to make money, and the fit modelling is paying the bills, anyone have any advice? I'd be very receptive to suggestions, just be kind. Looking forward to hearing some input....thanks all. I'm afraid i'm beginning to suffer from burnout!
