Cortisol isn't the only hormone in your body that's acting up, either. Dr. Anderson explained, "Adrenaline and norepinephrine are two hormones that the body produces in the face of stress. Both hormones push the response button by raising your heart rate, tensing your muscles, producing quick short breaths and making you sweat."
She added, "They shift blood and oxygen away from areas that might not be so crucial, like your skin, immune system and vital organs. Often loss of appetite, skin breakouts, headaches, and illness due to ineffective immune responses are the results. What you feel is a rush of tense energy surging through your system, a shortness of breath, foggy thoughts, and a pounding heart."
If you feel tense or overstressed, take a deep breath, meditate, or do something calming for yourself. You may not be with your ex anymore, but you can still give yourself the love and attention you deserve. Dr. Pinckney told me, "Meditation and breathing [have] been scientifically proven to decrease stress hormones, promote a sense of well being, and help you reconnect to the power within yourself as you go through this time of transition."
