for my guitar class we needed to do a project, and I decided to write a song.

the problem is, I blew it off.

If anyone has any catchy chord prgressions or riffs, it would be greatly appreciated.
Dude, you blew it off, so I think you should take responsibility for that! Anyway, how tough can it be to put 3 or 4 chords together?
So now you want the people of these forums to help fix your laziness. Plus you are in a guitar class, you should be able to put chords together. Maybe you shouldnt be in the class. You blew it off, sorry buddy.
