E: Eat right
Eating small, healthy snacks throughout the day will keep you energized and maintain your blood sugar level, which is key to avoiding irritability and anxiety.
Consuming a rainbow of fruit and veggies is important. And try to pass on sugary and high-fat carbs and opt for healthier choices, like pretzels, whole-grain bread and crackers and brown rice.
When something's bothering you, especially if it's something that can't be changed, usually it's best to just let it go. Focus on the things you can control and put in your best effort.
