I can't help think that also ties up to some mental health issues. Anecdotal, but I know a hypochondriac, a bad one, and I think a lot of her issues stem from anxiety of leaving her daughter behind if she dies or of losing her daughter (she's raised her kid to be one too). It became really clear this past year when taking to her how she thought every little thing she had waa Covid, even when it never matched the symptoms, and was always worried about how it'd affect her daughter.

She's also very much an overprotective parent in a lot of other ways, and I can't help but think the hypochondriac part stems from that.
