Why do you think people have suicidal thoughts?
Suicide thoughts may be caused by mental insufficiency, depression, hormonal issues, economic crisis, relationship problems, substance misuse, ignorance and existential crisis, or any crisis the individual defines as hopeless.
Consulting with a qualified counsellor or spiritual guardian, avoiding being alone, disposing of potentially dangerous weapons/substances, socialising more, improving economic conditions, and addressing the root causes of the case may be largely helpful.
