I feel like I'm a useless person. I can do nothing but guarding the door of my office. I have no friends and no one needs me. In fact, this feeling of being an outsider / an outcast has become stronger ever since I'm 20. But I had never realized that and casually spent my days until today.

Now I feel myself like a useless person. I can't do anything except guarding the door in my office. I have no friends and no one needs me. In fact, this feeling of being an outsider has become stronger as time has gone by since 20. But I have no idea of what to do about that and spend each day the same until today.
