I always feel so alone.... Nobody is ever home. My foster parent's always out of town, or when he's here he's always tired or busy with something. I have nobody to be with. Nothing. I want to be with someone. Maybe a friend would be nice. I don't want a pet though. You probably don't understand.
Could you perhaps try to find a nice neighbor near your age? Or as was already said, go out and take part in a church or park. Loneliness blows I know. But just get active and theres always people willing to be your friend.
It would be nice if you had siblings. I don't have many close friends, so if I need company I'd play with my siblings. If you don't, you'd best be looking for children of your parent's friends, or friends from schools.
