تعریف و معنای "[get] {sth} off {one's} chest"

What is the origin of the idiom "make a go of something" and when to use it?

The origin of the idiom "get something off one's chest" is believed to be rooted in the physical sensation of relief when a heavy weight or burden is lifted. The chest is often associated with the emotions and the heart, and when people have something troubling or distressing on their mind, it can feel like a heavy weight pressing down on them. Sharing their thoughts or concerns with someone else can provide a sense of release or catharsis, akin to the feeling of relief when removing a physical burden from one's chest. It is often used in situations where people want to express their feelings, seek advice, or simply share their thoughts with someone they trust.
