YANBU. I felt very sad and emotional the day Olivia Newton John died even though I know it was about to happen. I can still well up when I listen to her songs. It's very strange as I've never felt like that about any other celebrity.
It's not as if I've been a life long fan either. I grew up in the 70's with her guesting constantly on Saturday night TV programs, never bought her records (didn't buy any records really), so was just vaguely aware of her, then of course, Grease, Xanadu and Physical were top of the charts for weeks, so again, knew her hit records, but nothing else. Then she went off my radar from 82 onwards.
It was around this time last year when I was creating Spotify play lists and she popped up as a suggestion, so I started listening to hear, discovered lots of songs I'd never even heard before, then I found some YouTube videos of her performances, interviews, etc., and became almost obsessed with her. I found out she had a fascinating life, ancestry, etc., also her environmental and charitable work, and that basically no one ever had a bad word to say about her - she was genuinely loved by everyone - beautiful inside and out. By this time last year, she'd disappeared from public life, so it was obvious the 3rd cancer battle was about to be lost. That made me sad that I'd actually missed following her, missed the chance to see her live in concerts, etc.
On the day she died, it hit me very badly. Considering she was someone I only vaguely knew about (and forgot about), it was as if she'd been taken away just as she'd come into my life! That somehow made it worse. Still struggling to understand why it's affected me so much.
