feeling alone

I always get the remarks of, "You are not alone." whenever I tell people that I feel that I am. I feel like this shadow that passes through the day sometimes being able to interact with others, but only on the surface. I want to have people I can call and know that they are there to hang out. But I call people and it feels like they do not want to be around me, or they do and just do not want to make the effort. There are times when people call me, but it does not accumulate to all the times that I feel that people ignore me. I went off to Crown for school and none of my friends sat down with me to see how things were going with the transition, and when I would call up to see how they were, to see if they could get together it felt like a dead-end call. There was no effort, or no enthusiasm, to engage in me. Does everyone feel this way? Feel alone and incomplete? I do not know what to do with my time...God what do you want from me? I am trying to love the people around me, but when will I actually get a relationship with people beyond the surface? Is it my own fault? What am I doing wrong? What am I not doing? What should I not be doing? Because sitting at home alone after calling 30 friends who have no time to hang out with me is completely despressing. I just want someone to be there for me, and yet everyone is so busy all the time that we don't have any time to be there for each other. I feel alone, and it's no one's fault---no one is trying to make me feel alone---its just that everyone is busy all the time and getting through the busyness is more important than leaving it behind to get together with a friend.
