"How can I stay motivated to want to exercise?"
My answer is twofold.
2. I'd like you to give you something to think about as well: Here's what you listed as your daily intake of food:
Breakfast ~ mozzarella cheese stick, either oatmeal or a muffin; applesauce for a mid-morning snack.
Getting the motivation to exercise can also be directly impacted by your energy level and the nutrition that you're feeding your body. A cheese stick and a muffin in the morning will not give you as much energy as a handful of berries, grapefruit, cucumber with a little almond butter.
