It's an excellent first step. Suicide prevention lines are a wonderful way to engage people who are acutely suicidal in a moment of crisis.
What we need beyond that is a place to refer people once they have identified that they have a mental health need and that they're suicidal. The suicidality doesn't always go away; in fact, quite often it comes and goes in different periods of time.
We need to be able to connect them with supports and organizations like the Health Initiative for Men and other services that include mental health providers that are LGBTQ2S affirming.
