He was actually pretty depressed, he just refused to show it.

Feliciano Vargas appeared to be a happy-go-lucky teenager to everyone around him. Due to his excellent art skills and apparent nature, he was well-liked by most of his classmates. His family also prefered him over to his older brother, Lovino Vargas.

Perhaps it was that last fact that made his brother dislike him. And, truthfully, that was also the main cause of his depression, other than a slight bullying problem in school. Admittedly, it wasn't very slight. The ones who bullied him always teased him and said he didn't deserve to live. They always pointed out that his own brother never liked him, and they liked to snatch his sketchbook away and throw it in the rubbish bin.

To him, his art was his most treasured item. That did no aid to his depression; it only worsened it. When Feliciano asked Lovino if he found the art nice, Lovino would always reply "I don't like it, because it's yours" out of spite and jealousy. Most of the time, he didn't mean it, but it worsened Feliciano's depression a lot. To Feliciano, his brother's opinions were worth more than anyone else's, and knowing that his brother didn't like his art was a big blow to him.

Although he kept trying to improve his art, he began to feel as if he was useless. After all, his own brother disliked him and his art. And slowly, that was what drove him to attempt it.

By then, cuts already adorned his arms. He hid it well enough, no one suspected anything. Not even his best friends saw any change in his usual behaviour, and his family didn't either. Feliciano had pretended well, but even so, the mask had to drop. Before that, however, Feliciano decided to try one last time...

"Lovino, Lovino! Look at this painting I made! What do you think of it?" Feliciano said, grinning widely. The painting had been the two siblings. Feliciano was admiring a white lily, his favourite flower, while Lovino munched on a juicy tomato. This painting had taken Feliciano a long time to complete, as the bullies at school kept tarnishing the incomplete artwork. Lovino took one look at it. In his eyes, the painting was truely magnificient, but then again all of Feliciano's works were. He could never paint as well as his younger brother, which made him jealous. As a result, he made a rash decision out of spite...

"I don't like it." Lovino took the painting from Feliciano and tore it into pieces, leaving Feliciano extremely shocked and hurt.

"...Fratello... Why did you tear it up? Why...?"

Only then did Lovino realise the disastrous act he had just carried out. "I... I..."

"...It's because you hate it, isn't that the reason why? It's because you hate me, right? You hate me like everyone else does, right?"

"Feli, no, that's not why, I'm really sorry-" Lovino stuttered out, horrified by his own actions. His words were cut short by Feliciano's crying.

"Of course you hate me! Why wouldn't you? I'm useless! I'm nothing more than a waste of space, and I know that it's true! I don't need you to tell me!" Feliciano shouted at his brother before running away.

"Fratello!" Lovino called after Feliciano, but Feliciano pretended not to hear him. Feliciano was running away, and Lovino chased after him.

Feliciano couldn't take any more of the bullying in school, and the cold shoulder his brother always gave him. All he knew was that anywhere was better than then and there.

Eventually, he began to tire out and his brother caught up with him. But Feliciano had finally snapped, and he wouldn't listen to anything his brother said.

"I know I'm useless! I'm a good-for-nothing who doesn't deserve to exist! So don't pretend you even care about me, fratello! You never did!"

And with that, he raised the little blade resting in his hand and stabbed himself one last time, Lovino watching in pure horror.

"Ve~ Romano, do you want some tomatoes?" Italy asked his older brother as he made pasta for himself, Romano and Seborga.

"Sure. Hand one to me," Romano replied. Italy was fully aware that his older brother had been his blood brother in his previous life, and it made him glad to know that at least his brother cared for him now.

Italy Veneziano had been depressed, but no one realised it. He was a victim of bullying in school and ended up killing himself. His wish was to be happy and he also wanted a brother who would care about him that much more. And, in a sense, he did get his wish granted; both his brothers (Seborga and Romano) did care for him much more than Lovino did in his previous life. He did keep the slight "uselessness" though, but truthfully although in the second life he may have considered himself useless, no one else did to a serious extent. And that was what was important to him. (According to the theory, he hid depression and suicided. This follows the theory.)
