school project- HELP!

for school we are doing a poetry anthology project. My topic is broken friendship. Does anyone know of any famous poets that have good poems on that? We need to have poets that have been published..im so mad that we can use poems from here and give you guys credit b/c some of you are really talented! But if you know of any poems let me know! THANKS!

my friend had to do a project on self harm. and she couldnt find any poems that she thought were good by famous people so she made one up herself and made up a name! it worked a treat!! good look! xxxxxxxxxxxxxxxx
