If they're also experiencing sexual violence, I 100% of the time always suggest Pittsburgh Action Against Rape. PAAR offers free therapy and finds legal services for sexual violence survivors. They helped me find legal counseling with a pro bono attorney that helped remove my abuser from my home.

The other suggestions are also good. Help keep horizons broad. I hope they listen to you before it's too late. You can't force them, but you can be there for them.
