struggling

Hi all,
I have been struggling a little bit. Mostly dealing with foods that are not mine, too high in calories and nutrient poor.Exercise is getting started for the first time in forever I exercised 2 days in row. This is taking a lot out of me. Taking care of myself. Mostly because I take care of others. I'm just not so good at this. How do you learn to take care of yourself with comfort. Any help will be appreciated.
Michele
