Exactly, thanks for putting it in simple words I absolutely do not care or even think nostalgically about the phone I left behind yesterday now, because I've set up and used the new one enough already to know it works well and it is better than the previous phone. I actually procrastinated the upgrade for a couple months mostly because I had to travel and was worried, what if the new phone will not function properly (there is a moderately complicated process to set up email and data transfer on new devices in my job)? But, as often, my worries were exaggerated - all that has been set up and works perfectly now. I would certainly not want to get the old phone back now with its ~zero battery life and other limitations.

I was thinking how much this experience is similar to my interpersonal relationship patterns? There is definitely a strong motif of initial brief anxiety but then typically moving on pretty quickly, what I see usually more quickly than many other people. This is not really the case when I was truly attached to someone based on years of good experience and strong bonding (e.g. my father, a few close friends and partners) but even those separations, they do not typically cause serious disruptions in my life. It might sound weird or even inappropriate to some to compare "attachment" to inanimate devices with people, but these were my thoughts today.

Yes, the initial what if's. Well, that's why the diagnosis Generalized Anxiety Disorder fits me usually. But I actually tend to get anxious about practical things way more often than interpersonal things...
