Accept it's going to take time. Trust the process. You won't always feel like doing the work. Do it anyway. You might have a bad day, write it off, and get back on track. Find activities you enjoy and fit in with your routine. Log your weight every day, the good, the bad, and the ugly. We are all in the same boat.
Accountability and maintainability. Lifestyle, not a diet, progress, not perfection.
It IS doable, and you can do this.
