Gestational diabetes

Since I am recently diagnosed with gestational diabetes, Im having a hard time dealing with it. 1. Eating on a schedule is difficult since my work time is different everyday 2. Not enough time to cook to be eating on time. 3. Food choices are very limited 4. Hard to eat snacks when im at work. 5. Having hard time poking myself 4 times a day How do you cope with it if you also had gestational diabetes before?
