My final decision has come to "drop it" too
But I'm curious to find out

Why not stress it?

Just for argument sake, would you tell me why not?

reason being, I spent time doing the work. The others? They did not spent time doing their research. And now they are reaping the benefits of my work.
I get that I'm mad at myself for being too simple-minded (as in just turning in my work early and didn't think much about using my ideas as template for their work).
