I don't know what I need right now

Hi everyone, I'm making a post for, well I'm not sure why. I just kind of feel lost at the moment. There was a time when I told myself that I would never feel this way because I genuinely felt it but now I don't know. I'm not even sure why I'm making a post to be honest. Maybe I just wanted to get my thoughts and see how others view them as to whether they're healthy and normal or not. I feel I'm going through the motions. I have no friends. I have no desire to make friends. My job search is not going well and my college life is monotonous. I think there is a root cause to this. I had this friend last year. She made me want to change, to reach out and form connections to others. Well she's gone now and that's my fault but it just goes to show how screwed up I am in the head. I don't know what I need or why I need it. I feel empty inside. At this rate, the world could keep spinning for 100 more years and I think I'd remain the same. I don't know if I'm looking for words of encouragement or any advice in general, I think its just nice to hear other people's opinions about my thoughts. Thanks for reading this.
