I just hope this doesn't turn into a hate thread (OP you might want to include some positive emotions in your opening post).
On topic,
Jigoku Shoujo(season 1 and 2) - sad and furious(at some of the characters).
Maria Sama Ga Miteru -
Very giddy
School Days - Furious at myself for sitting through it.
Grave of the fireflies,
5cm per second,
Elfen Lied - Extremely sad.
Clannad and
Clannad Afterstory - Mixed bag
And a very, very special mention for
Berserk - Awestruck and horrified.
P.S. there are plenty more but these will do for now.
