The crazy thing about toxic levels of stress is that it can lead to a brain chemical melt down. Once you experience what I like to refer to as a “brain melt-down” you are then much less equipped to handle the stress making you feel even more irritable or depressed.
Serotonin (a potent brain neuro-chemical) has a profound effect on mood and behavior. When someone is experiencing high levels of stress, serotonin levels often fall, creating a domino effect of; over-reaction, irritability, anger, tension, emotional upheaval, and often depression. Declining serotonin levels also can lead to sleep problems, excessive cravings, and weight gain.
