Why wouldn't you have strong feelings for a place that was your home? A home that is no longer available to you, that is essentially being taken from you?
Working through the loss of people, places, and things -- as well as such things as a slow decline in good health and physical and cognitive functioning -- can be painful, but it doesn't preclude us from planning for a slightly or majorly different future. Maybe even a better one? It's alright not to know.
Making a decision to just "let things go" doesn't work and only delays the process. A form of resistance. Acknowledging the extent of the loss and the intensity of the feelings attached to it might help.
There is no such thing as rules or a user’s manual when it comes to separating from the things we love. We grieve differently, we don’t all express love in the same way, and we struggle in different ways as well.
You’re the boss, Alex.
