I've learned that loneliness is relative. You can be in a room full of people and still fill alone, and be completely by yourself and not feel lonely at all. I'm sorry that you feel lonely right now. I often feel that way, and that no one understands, However, I have found that if you do in fact feel this way, this is one of the best places to be. A lot of people here share the same emotions that you do. Welcome to PC.
