I don't know what exactly what it is I intend with this blog...

I don't know whats going on. I'm 23 years old. I am a supervisor of security at a local shipping company. I am making decent money so no real complaints there. I just don't know. I have no girl in my life. And I am at a point where I would like to be with someone to spend time with and just be able to be myself with and relax with. I am now a brand new business owner of an online business. Literally i just started today. I am full of fear about the whole thing failing. I am afraid of being alone for good. I am afraid of being the guy who shuts all his friends out. I am afraid to live for fear of loss. Which means that I lose anyways because i lose the experience of truly living. What the hell am I supposed to do?
