I need help from a stranger.

My girlfriend recently started seeing a life coach but I'm afraid that it might not help her fast enough.

Tonight I used her phone to google something and I saw a open tab "How many pills does it take to die". She hasn't self harmed recently as far as I know but she does struggle with the urge and did do it. And she frequently admits that if it wasn't for me she would probably have done it.

I've had friends and family members attempt suicide and I've personally stopped a friend from succeeding, but I'm way out of my depth and I need advice
