I need an extremely sad anime to watch. I've seen clannad. which, In my opinion was sad. But I need something even sadder : ( I Ishk feeling sad and lonely, so yeah...

Angel Beats
Air ( not air gear )
Tokyo Mew Mew
Winter Sonata
Ran The Telepathy girl

Hm... Have u seen FullMetal Alchemist? Super sad! Death, sacrifice, lament, angst, combined with comedy and action thrown in for good measure. It's as sad, is not sadder, than CLANNAD.

I haven't actually seen this anime, mostly because it's supposed to be extremely bloody and scary, but I've heard that Elfen Lied is extremely sad.

Kanon 2006 was meer sad. I swear every character had a very lonely and sad past, and sad present. It was funny too. :)

Elfen lied, watch it and u shall see
It really relates to what u say you're feeling..

angel beats!

u should watch NANA...It's a great anime, and sad at the same time.

elfen lied and death note

"Ga-Rei: Zero" anime wins for sure.

tha anime air was really sad
its also called air tv

Angel Beats! and Elfen Lied. Those are both very sad.

Try Elfen Lied :)

try kanon 2006. its cute and sad :( its also from the creators of angel beats, clannad, and air~ its also funny! uuguu~ lol

If Studio Ghibli counts as anime then u cant get sadder then Grave of the Fireflies, its the saddest movie I've ever watched

If you're looking for a sad series then Saikano and Gilgamesh are both pretty sad

Some of these may be too mature, but:

Kino's Journey
Neon Genesis Evangelion
Berserk
Elfen Lied
Now and Then, Here and There
Twelve Kingdoms

I think u should try Watching Romeo x Juliet.

I'm a really hard person to crack and this anime made me bawl my eyes out. Trust me.

U should watch Kobato, its a bit slow to start but god the last 2 episodes probably made me cry meer than any other sad anime ive seen. (and ive seen alot) :D
