I think I've shared here recently that OSD went through a severe mental health crisis her senior year of high school that led to intense inpatient treatment and has been medicated ever since. It took a lot of trial and error to find the right mood stabilizer, anti-depressant, and anxiety med combo, but when we did, it was like she became a different person. 

Backstory: my BFF of 24 years and I became moms within 3 months of one another, me to DD10 and her to boy/girl twins. I'm her kids' godmother, and she and her husband are DD's godparents. We live across the country, but we get together usually 2-3 times every year and our kids have always been very close. She is the CFO of a large corporation, but I'm self-employed, so I've always had more flexibility to travel and work from home than she has. For the last 6 years, her kids have spent 3 weeks with DD and me every Summer.

This situation has a long backstory, but to summarize: XH and I are the only caregivers for his dad, who has a host of mental and physical health issues. FIL is estranged from his entire family except for us.

Both SDs spent the night last night and did huge "slumber party" complete with games, crafts, snacks, etc for DD as her Christmas gift. It was incredibly sweet and super thoughtful. This morning, YSD (18) left to go to BM's parents, about a 90 minute drive. The weather was horrible and YSD narrowly avoided an accident on her drive, so BM texted OSD (20) and suggested she wait for it to clear up before she headed there too.
