PS:
I found someone who could take on the PA posiiton, helped the new SM with spreading the news of the change and offering support. We're going to have a private memorial at the theater on Saturday before one of the four shows (we're in rep). Last week, I found a counselor at the local college who was volunteered to be "on call" for a few days to help. And I talked to a local catholic priest who volunteered some time to the couple of cast members who had some really strong moral concerns, so it eased their pain.
There were still a lot of tears and hugs last show, but overall, the emotions have mellowed with time and it's nice to get a full night's sleep rather than having to respond to a 3:30 phone call from a really depressed cast member. And the company has now seen me work with the new SM, so they feel some sort of comfort knowing that it's "back to normal."
As for the Production Manager... I'm not sure where he has been, but it seems like once the shows open, the PM just kind of vanishes. The company is only a 30hr/week SPT contract so I knew that I'd have to pitch in more than when I was working larger companies, so this has been a good learning process.
Thank you for the advice and tips. I felt so... overwhelmed when the admin staff and cast both turned to me and wanted me to do something. And with all that I've experienced with performers having emergencies, I thought I could handle this better than I did. Anyway, hopefully I won't have to face this situation ever again.
And now I'll get a chance to grieve before I go into tech for the new show.
Thanks again!
