I don't have much to say except, I know what you mean.
It's human to feel a jolt when something that has jolted us before shows up again. I have felt this way about the phone, my doorbell, emails and letters.
It gets easier the more we let go - and at the same time I wonder if it ever goes away.
I hope you both give yourself time to read it when it feel right and that you find support for how you will feel depending on what it says.
Prayers...
