Stress, Anxiety and Depression

Stress is mental tension caused by demanding, taxing or burdensome circumstances. Stress doesn't just affect our mental state and mood; it affects our physical health as well. When we are very stressed, a hormone called cortisol is released into our bloodstream, suppressing the functioning of our immune, digestive and reproductive systems. When the stress response fails to shut off and reset after a difficult situation has passed, it can lead to depression in susceptible people. Depression is a common but serious mood disorder. A person's thoughts, behavior, tendencies, feelings, and sense of well-being are all affected. Depressed mood is also a symptom of some mood disorders such as major depressive disorder (MDD) or dysthymia. Melancholia is a state of low mood and aversion to daily activity. Anxiety is an inclination depicted by a hostile state of internal turmoil, every now and again took after by anxious conduct, for instance, rumination, and so forth. It is the subjectively irritating feelings of dread, for instance, feeling of downfall. Pressure isn't the same as fear, which is a response to an honest to goodness or saw incite hazard, while apprehension or uneasiness is suspecting future risk.
