Why so attached to necklace that bought six years ago, haven’t taken it off sense. feel an immense amount of anxiety and start to panic if think about taking it off. Why?

It’s the kind of “end of an era” feeling you get when you commit to something, be it a joke or a habit, or even a relationship. When you invest time into something, be that accompanied with meaning or not, you don’t want to let it go because that thing is now a certainty in your life. Taking the necklace off is removing that stability, that constant, that era. It’s deeper than you have to think about it but I hope it makes sense.
