Yes. Completely. My husband is 21 years older than me and I'm terrified of him dying. Not just of old age before me-he has an hour journey on the motorway to work each day which leaves me very anxious. He does everything for me although I have lived on my own and could do everything myself. But the main thing is; he's the only one apart from my t who sees the real me. I'd he utterly lost without him. I'm always saying to him, please don't leave me, don't die. I work on it in therapy cause poor man is under a lot of pressure not to die. I love him so much. I completely empathise with you. Btw the age difference is interesting because an ex boyfriend of mine died of a heart attack (fit and healthy) when he was about 33. Not very helpful I know; but age is no indicator.
