I need some opinions/advice

So my best friend of 10 years has always had social anxiety and didn't like to be around people alot. But over the past year it's gotten worse and with her parents recently splitting up her stress has increased a lot. She's been having feelings of depression and she tells me everything which I am do thankful for. But the other day she texted me and said she needed to talk to me because she's been having thoughts about hurting herself. She said she would never do anything and that she doesn't want to but she just needs something to take the pain away. She will be starting anti-depression and anxiety medication. And she is going to a therapist soon. I just don't know how to make her feel better or how to "comfort" her.
