What Causes Suicide?

There is no single reason behind suicide. It often happens when life's challenges become overwhelming, especially for those struggling with a mental health condition. Depression is the most common condition linked to suicide, yet it is frequently undiagnosed or untreated. Other conditions such as anxiety, substance abuse, and other mental health struggles can also raise the risk, especially when left unaddressed. However, it is important to remember that many people with mental health conditions manage them successfully and lead fulfilling lives.

Suicide Warning Signs

This is especially concerning when these changes follow a difficult event, loss, or major life transition. Most people who die by suicide show warning signs, whether through their words or actions.
