Very rarely are people actually coerced to do something against their own free will, forcibly. Typically the coercion is more insidious, sneaky and low-key: fear tactics include potential loss of income, blackmailing personal family information, or other forms of coercion.
Why does this difference matter? Well, realize most people will not coerce you to do something against your own free will in your face; they will do it against you in far more sneaky and hidden ways. Thus when you are pressured to do something or make a decision take a step back, pause and delay. Wait at least 48 hours before making the (potentially irreversible) decision.
