Well, I talked to LCM today. We scheduled something for 5pm tomorrow despite talking for 45 mins today. She sounds okay and said she's doing a lot better.
We agreed that we need to have a schedule this week so this doesn't happen again.

At the end, I told her "please don't die". She laughed. I asked her why she was laughing and said I was dead serious. She said "you're right. I shouldn't have laughed. I find it super adorable that you care so much". No, you don't even understand... I emailed her most of what I posted here because I feel like she should know that this situation upset me so much that I was bracing myself to find her name in the obituaries.
