Well, wecome to the crazy club 
I understand more than I would like to know.
Early on, I bought a complete set and had them for years in my china cabinet. Decided I'd never use them, so they got boxed up and donated.
Fast forward an unknown number of years. I saw them and bought them AGAIN! And, like you, I had to have extra dishes. It is just insanity.
I'm confessing so you don't feel alone
Maybe something in our childhoods?
I've never seen the big platters again, and I am really sorry I gave those away.
However, in view of ALL that, I remind myself daily that I no longer entertain and it is just me and my husband. All those dishes just gather dust, but I do enjoy looking at them.
Maybe we will be lucky this year and they won't show up!
