It's an old adage, but it's true. Time heals all. There's no problem that won't get better with passing time, and some care and attention.
Give your problems time, especially when it comes to losing weight.
You did not develop an overweight or obesity problem overnight – it took years. So it will help if you give solving the problem as much time as you took to develop it.
While you wait patiently, do your best at all moments, and keep God as your partner.
