This happened to me a while back. Go to your doctor and have your blood work done. Many factors can be signals of being overstressed. Vitamin D can be very helpful with anxiety and other hormones that are off can be leveled out with proper eating and in some cases medication. Our bodies do send messages in interesting ways. Also look into food allergies. These can really have a huge impact on your overall health. Meditation is a great addition for most people in handling stress. contact me for more info.
