How to deal with a suicidal friend?

Miss J

I am here to look for advice. My best friend is stuck in a city 3 hours away from me (can't travel due to covid). She is in a highly toxic environment where in her own words, everyone makes her feel worthless and she keeps saying she just doesn't want to live. Partner and family are not helping as far as I know.. She's got a toddler that takes lots of care so it's also hard to keep in touch.

Any advice will be greatly appreciated.
