Giving yourself the benefit of the doubt is something you might need some help with. There is a tendency to judge in each of us, try to be as kind to yourself as you would your best friend when giving them a pep-talk. Give yourself the freedom to take care of yourself first, in doing so you will be better prepared to help others when they inevitably need your support. Check-in with yourself daily about which foods feel most nourishing for you and your exercise regimen. Small changes that you can actually stick with will have a greater effect on your health in the long term than huge changes that are too difficult to maintain.
