So I come online a fairly-distant-but-fairly-close friend of mine comes on and tells me he went into rehab and kicked his cocaine and alcohol habits. Good.

However, now he's homeless. He said he couldn't deal with it anymore and he told me he ODed on antidepressants. He then went offline to apparently call his mother. He came back on later, said he couldn't call her and started giving me instructions.
Including the phone numbers of his ex (who kicked him out of the house) and his parents.

I told him to keep typing, tell me what he took, where he was etc. I'm not sure if the address he gave me was real or not (in a different city btw), but it got to the point where he was barely legible and complaining about being woozy and foaming at the mouth. I called for an ambulance and am now just waiting patiently.

Will they call me back? Or will I never know what happens? What do I do?!
