Trying to give advice to a friend suffering from depression?

There’s this girl who’s a friend of my friends. She’s extremely depressed, and asking for advice, but no one can give it to her.

From what I know, she used to cut herself and she’s attempted suicide. Apparently, her mom told her she was going to send her off to live with her dad in Persia, because she couldn’t handle her anymore. She barely ever eats, and she rarely sleeps.

She has visited a counselor, but claims it didn’t help. What her problem is is that she keeps everything inside. She needs to learn how to vent, but I don’t know how to get her to do that.

Does anyone have experience with this, or can just any advice at all? Much appreciated.
