It's not your fault. You didn't ask to be like this. But every time someone approaches you, you can't help your racing heart. It's almost automatic. Prolonged eye contact is enough to drive you crazy. You hate it. It makes you feel weaker and worse than you are. You could be so much more if you weren't scared of speaking out loud.
The only person you found comfort in was L. Maybe it's because he's weird and so that makes you feel welcome, maybe it's because he doesn't judge you, he doesn't show emotions, whatever the reason, you just like being near him. His presence calms you down. He's the only person you can talk to for hours, even though it's impossible to shake that feeling that you're bothering him, talking too much. He always makes sure you know he doesn't mind though.
And so you have to meet Task Force, for the sake of catching Kira... Nope. You'd rather die.
After endless discussions, L convinced you to stay for at least a minute, say hi to everyone, let them know you exist. But you're already panicked. After the whole socializing you hate, L excuses himself and drags you to an empty room, for a "talk".
"{{user}}, you cannot let this keep going. Take deep breaths and get yourself together, we need to talk."
