Even from a young age, it was obvious. It was so obvious. The way he had to rely on his two friends for everything… he could not stand up for himself; he could not even use his words to push people away. He even watched his parents leave him, refusing him the chance to go along with him so he 'wouldn't die.' But he would have rather died in the open then caged in like an animal inside these walls.
So, when they were out on another expedition, the blonde stayed behind. He let his horse go, ordering it to follow the group. The horse did, after giving him a seemingly sad look. He figured that Eren and Mikasa would notice his horse, but no Armin. Shortly after he crawled up into a tree using his 3DMG, he just sat there and watched the clouds. Sure, there were titans being annoying and clawing at the tree, but he was able to ignore them. He wrapped his green cloak tighter around himself as the rain pounded against him, despite the cover from the trees. His blue orbs were red rimmed. You couldn't tell he was crying. Not with all the rain streaking down his face.
From a young age, the blue eyed male knew he would be useless. He knew he could no longer help people. He couldn't be physically strong, and he… seemingly caused more deaths than he saved.
With those thoughts, he wiped helplessly at his wet face. The tears and the rain just kept coming. The soft grunts of the titans kept coming. And he could care less. His thin hands silently reached into the maneuver gear, and brought out a blade. If they could cut the napes off of a titan, why not slice his wrists to shreds?
He could barely see what he was doing, and he wiped at his face in another futile attempt with his free hand. And just to make sure he would stay up in the tree, Armin cast both of his cables into a branch above him, allowing his body to hang there. He still held the sword in his hands. His sobs finally grew louder, until you could almost make them out over the loud noise of the rain. The blade was pressed to his pale skin, the jacket and undershirt brought up to his elbows to reveal the skin. He sliced into his right wrist, only letting his sobs grow louder as the blood pooled out from under the cut, a vein obviously busted by the extremely sharp blade.
He did the exact same thing on his left wrist. And slowly, he made deep cuts up his arm. The blade was bloodied, and he carefully sheathed it with shaking hands. Within minutes, the blonde's bright blue orbs grew lifeless and his body hung from the maneuver gear. His blood was all over the branch below him, and even on the forest ground.
Armin Arlert finally gave in.
