Feel better?: So sorry you have been under such stress! time to make some changes. Reduce the stress where you can by getting the proper emotional support you need. Change your dietary habits to one with high nutrient intake (high in brightly colored fruits and vegetables) and slowly begin to engage in an enjoyable form of exercise. Keep it fun!
