We can change societies in a few ways to reduce the number of people that reach her situation. That's going to take a very long time. Another thing that could be done is creating a plan for people in her situation. I think this will happen in the future (and will impact society in general). It has to do with the use of psychedelics. It may sound crazy to some, but I'd recommend we give people like this some shrooms, then escalate that to something like Ayahuasca and then DMT. If she still feels like nothing is worth it at that point, so be it, but I believe she'd change her mind on this path and have the potential to live a much happier life. This comment may seem extreme now, but looking back, I don't think it will be.
