The thoughtful listener
A life can satisfy the criteria you were given without meeting the needs you actually have. Security, achievement and being loved matter; they do not make disappointment impossible, nor do they reveal everything happening inside you.
I would be curious about whose word "good" appears in the question. Your own? Your family's? The imaginary observer who would inspect your circumstances and tell you that you have no right to complain?
You need not dismiss what is valuable in your life to acknowledge what feels absent. Gratitude and unhappiness can occupy the same room.
If the unhappiness persists, affects daily life or becomes difficult to manage, a qualified professional can help you explore it. You do not need a sufficiently impressive tragedy to deserve support.
