Synonym discussion
Sense: adjective/1
All four describe an unhappy reaction to something, but they differ in cause and intensity. 'Disappointed' is the mildest — it only requires that something fell short of expectations (a poor exam result, a cancelled trip). 'Dismayed' adds worry and a touch of shock to the disappointment, usually because the bad news was unexpected; you are dismayed by sudden announcements or unwelcome discoveries. 'Disheartened' shifts the focus to lost motivation — after repeated setbacks, a person feels disheartened and may give up. 'Appalled' is the strongest and carries a moral charge: it is reserved for events you find shocking or wrong, like cruelty or serious mismanagement. So 'I was disappointed when the picnic was cancelled', 'I was dismayed to learn the company was closing', 'I was disheartened after my third rejection letter', and 'I was appalled by the way he treated his staff'.

Etymology
From the verb 'dismay', which entered English in the 13th century via Anglo-French 'desmaiier'. The root combines a Latin negative prefix with a Germanic stem meaning 'to have power' — so the original sense was 'to deprive of power or courage', which over time softened into the modern meaning of being shocked and discouraged by bad news.
