Vitamin C Foods
If you are deficient in Vitamin C, then, you will notice a difference in your mood. You will be slightly irritated at times and you tend to be anxious and nervous even of the smallest things. The only way to combat that is by boosting your immune system and protecting it from toxins that can cause you to be anxious. You could eat oranges, potatoes and leafy veggies to load up on your Vitamin C.
