I unfortunately have the same feeling. Around Iphone 4 or so (when they were a lot smaller and sleeker) I got a slim phone case that could hold a card and my ID. It felt so nice going on a trip with only that in my pocket (not having to worry about if I feel my wallet in my back pocket, etc) but I couldn’t get over the fact that if I lost the phone I would be utterly screwed and a long way from home. Tend to always have a back-up now adays since I don’t want to have to put up with that.
