I know what you mean. I'm 55 and have a special plate I eat almost all my plated meals on for the last 35 years. It's a melamine platter that is sized perfect. This plate allows room for cutting the meat/veg without mixing everything together. My wife thought I was weird at first, but now just serves it up on "my plate" everyday.
I love it that you've been using your dish for 35 years! I think it's such a nice, comforting thing to have---your own spoon, your own favourite dish, your own cup, whatever! And you can really get attached to them because it's something you use everyday. AWESOME!
