Suicide Prevention in Nassau County and Across Long Island
Nassau County suicide deaths are part of a wider crisis across New York and Long Island, and the county is not exempt.
The CDC recorded 1,701 suicide deaths among New York State residents in 2024, an age-adjusted rate of 8.1 per 100,000, with the sharpest risk among adults ages 50 to 54. That toll reaches across Long Island’s towns and villages. Nassau County answers it with a coordinated crisis system, pairing a county Behavioral Health Helpline and Mobile Crisis Team with the Long Island Crisis Center, which fields 988 for the county. A free line that picks up around the clock helps close the gap between a breaking point and the help that meets it.
Who This Hotline Is For
Anyone in Nassau County who feels overwhelmed, hopeless, or unsafe belongs on this line, and so does anyone frightened for a family member or friend. A life-threatening emergency is not a requirement for calling.
Callers reach out over suicidal thoughts or urges to self-harm, over anxiety or grief that has grown too heavy to carry alone, after a sudden loss or upheaval, or simply because the middle of the night feels unbearable and they need a voice. Parents, spouses, and friends call too, when they see someone they love slipping and are unsure how to step in.
Connecting You to Nassau County Care
Beyond the call itself, this line works as a bridge into Nassau County’s own crisis system, from the county Mobile Crisis Team to Long Island outpatient providers, so a single phone call can open the door to help close to home.
- Around-the-clock access: counselors answer at (866) 629-4564 through nights, weekends, and holidays, when many Nassau County offices are closed.
- Local resource connection: referrals to Nassau County therapists, the county Mobile Crisis Team, outpatient programs, and support groups matched to what you need.
- Guidance for loved ones: coaching for Nassau County families on spotting warning signs and stepping in when someone may be at risk.
- A path to treatment: counselors explain therapy and treatment options in plain language so you can choose what fits on Long Island.
What Happens When You Call
Dial (866) 629-4564 and a trained counselor picks up, ready to listen without judgment and to keep your safety at the center of the conversation. No recorded menu, no waiting on hold, no script to sit through.
You set the pace. The counselor works through what is happening with you, helps the moment feel less overwhelming, and maps out one manageable next step together. When it fits, that step can mean a warm handoff to Nassau County services such as the county Mobile Crisis Team. The conversation stays private, and giving your name is never required.
Nassau County Warning Signs Worth Noticing
The moment to reach out is when the first warning signs appear, in you or in someone close, not after a crisis has already taken hold. There is no need to wait until things feel impossible.
Pay attention to talk of hopelessness or of being a burden, a pulling-back from people and activities that once held meaning, abrupt changes in sleep or mood, the giving away of things that matter, or a rise in drinking or drug use. Spotting even one of these, in yourself or in a Nassau County neighbor you care about, is reason enough to dial (866) 629-4564.
Knowing Which Number Fits Your Situation
Two numbers, two purposes. The table below sorts out which fits your situation, and when danger is immediate the answer is always 911 or 988 first.
| 988 Suicide & Crisis Lifeline | Depression & Crisis Hotline | |

| Hours | 24/7 nationwide | 24/7 |
| Also offers | Text and chat, Veterans and Spanish lines | Referrals to local therapists and depression treatment |
When the danger is immediate, 911 or 988 comes first. When you are struggling and want a person to help you weigh options or find ongoing care on Long Island, a trained counselor is there to talk it through and connect you with what is nearby.
