Where are my 20's going?

I was reflecting on the last line of my last entry. "What a way to spend my 20's" All I keep thinking is what the fuck is wrong with me? Why am I letting this time in my life slip away without a fight? I sit at home and dream about meeting new people yet hardly ever put myself in a situation to meet new people. Why do I do this? My only answer has been that I'm scared. Well that is kind of broad. Scared of being hurt and not just emotionally, but physically (I place part blame on cop shows where at least one girl seems to die or get raped every week). I realize that my fear may not be completely rational, but who ever said that fears had to be rational. I fear that I'm going to go out and not meet anybody which would be a big let down or end up in a dangerous situation. I don't know what to do to change these behaviors. I could go to the bars by myself or try actively pursuing some postings on Craig's list, but I get so nervous even thinking about it that I have myself psyched out before ever really getting into those situations. I have no real solutions to my current predicament. Frustrated is the best description. I might have more thoughts developed in the morning.
