I was terrified of asteroid impact and meningitis. I am a migraine sufferer, and every time I got one I was convinced that was it.
Also, I used to cry with intense melancholy at loads of things when I was a kid. I had a keyboard that had a version of Just The Way You Are as it’s demo, wept at that. Learned to play the piano, used to play and sing through an Elton John song book and cry, particularly No Sacrifice. Still have trouble listening to A Good Heart by Feargal Sharkey sometimes, because while it was my favourite song as a kid it can tip me right over the edge. It was on in Co-Op a while ago and I had to leave.
