Constellation that failed to save others' tears

Never cry in public, not to be brave, but three strong enough constellations. Do you know which ones?

Capricorn Capricorn usually solves any difficulties by itself and does not need help from others. This is not because they think highly of themselves and don't want to trouble others, but because they believe they have the ability to face all the difficulties at hand. Capricorn will not cry openly even if her heart is broken.
