My "Notes" application on my Mac doesn't respond when I open it.

A day ago, I was looking up something on spotlight and saw a peculiar entry from notes I thought I deleted. I clicked on it and a small box with the note in it appeared. It stopped resonding when I tried to edit the text or close it or anything. Now everytime I open notes, that same little note box(not the full sized one) comes up and doesn't respond. Every single time I open notes. I am forced to "force quit" every time. I have tried restarting, shutting down, nothing sems to work. Please help. This is getting very frustrating very quickly.
