Today, San Isidro ISD joins communities across the world in recognizing World Su***de Prevention Day.

A simple conversation, a moment of kindness, or checking in with someone can make a difference. Together, we can break the stigma, spread hope, and remind one another that you matter, you are valued, and you are not alone.

If you or someone you know needs support, call or text 988 to reach the Su***de & Crisis Lifeline—available 24/7.

A brighter tomorrow is possible. Together, we are stronger.
