Sanctioned suicide means that someone is allowed or given permission to end their life. This is only done in very specific and rare circumstances, such as if someone has a medical condition that is causing them a lot of pain and can't be cured.
However, this is not the same as someone just wanting to end their life because they are feeling sad or overwhelmed. Suicide is a very serious thing and should only be considered in extreme cases when all other options have been explored.
So, to put it simply, sanctioned suicide means that someone is allowed to end their life for a very specific, medical reason. But it's important to remember that all life is valuable, and suicide should only be considered as an absolute last resort.
