Why does it seem that the entire premise of therapy is overwhelmingly centered on preventing suicide?

It strikes me that there's a lack of acknowledgment for the perspective that, for some individuals, the desire to exit this life might be a considered and steadfast viewpoint.

Certainly, there are instances where feelings of wanting to end one's life are fleeting or influenced by transient challenges such as financial difficulties. The prevailing wisdom suggests that with time and support, these feelings may pass.

However, what about the scenario where an individual genuinely finds life unendurable, not due to acute crises but as a fundamental assessment of their existence? Every person is thrust into life without a say, and upon evaluating their experiences and the nature of existence, some might conclusively decide that it's not for them.

The question arises: should there be space within our societal and therapeutic frameworks to validate and discuss these feelings without the immediate jump to suicide prevention strategies? Isn't there merit to considering the depth and nuance of such a stance, especially in a world where autonomy and personal choice are highly valued in other contexts?

Edit to bring attention to this comment.

Edit to steal the line "Life is a gift that nobody asks for, and so, in return, I think it should be free to refuse".
