Why do psych meds make your condition even worse than before when they are discontinued? it is as if you can't ever go off bc it will do the opposite

Perception: Say U're outside & U're cold. Someone lends you a warm hat.U get warm again.Now they're leaving & need it back.When U take off the hat,the warmth escapes & U feel the cold more b/c U were just warm. If a psych med is working,people often think,"I don't need this"& go off it.Often,the condition returns, & now they feel it more intensely because they know what it's like to live without it.
