I need an extremely sad アニメ 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...

エンジェル Beats
Air ( not air gear )
Tokyo Mew Mew
Winter Sonata
Ran The Telepathy girl

Hm... Have あなた 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 もっと見る sad. I swear every character had a very lonely and sad past, and sad present. It was funny too. :)

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

エンジェル beats!

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

elfen lied and death note

"Ga-Rei: Zero" アニメ wins for sure.

tha アニメ 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 エンジェル beats, clannad, and air~ its also funny! uuguu~ lol

If Studio Ghibli counts as アニメ then あなた 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 あなた should try Watching Romeo x Juliet.

I'm a really hard person to crack and this アニメ 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 もっと見る than any other sad アニメ ive seen. (and ive seen alot) :D
