As others have said, we do care. *hugs*
Loneliness does feel really devastating... It slowly tears apart every last hope from you. The feeling of being alone in the loneliness, that no one understands. It's this huge draining feeling of emptiness. It makes you feel forgotten, neglected, invisible, unworthy, lost, pathetic, frustrated, depressed, gloomy etc. I feel really lonely even if people care, but the reason for that is, that the only people who care are online. Even if there are many caring people online, who are ready to listen or talk, it's never same thing as real world where you can talk face to face or get/give a real hug. Of course everyone of us are real, even if it's online or not, but it's not as real as real life.
