text:  The 9-8-8 suicide and crisis lifeline turns two tomorrow in a new poll finds most Americans don't know much about it. However, NPR's Meenu Chatterjee reports among those who contacted 9-8-8, the majority say they got help. The NAMI poll found that 23% of respondents are very or somewhat familiar with 9-8-8, and only 3% said they or a loved one had contacted the number during a mental health, substance abuse, or suicide crisis. Hannah Waslowski is chief advocacy officer at NAMI.
