I know you say you don't have time to read labels, prepare foods etc, however isn't it worth spending the time to do these things for a few months to set yourself up with the knowledge of what you can eat and how it effects you, along with creating healthy habits, then once you have the knowledge you can use it to make quick and easy food choices.
Take some time to learn what works for you, to learn some healthy tasty recipes and have some back up plans for those nights when you really are just too tired to prepare anything. It's important you prioritise some time to do this for yourself. At the end of the day, if you don't, and get sick, you won't be able to fulfill your other commitments.
