The death of my social life

A bank holiday weekend. Hurrah I hear you cry. We have a few extra days off work...yes yes we do. Although for me while I also have the sense of OH THANK HOLY GOD I'm not in work, I also have the dread of, what am I going to do.

As you, dear reader, may have noticed I am trying to widen my social circle. Which is harder than it seems. As someone who has spent most of his adult life on the Internet and not gone out its difficult to teach yourself when your 24. When I was younger, I used the Internet as a way of hiding, making friends in places where they wouldn't know me, and couldn't spread my secret. And that was a substitute for actual physical friends.
Now that I am in London I want people to go around with, someone to take me to the little known place that's off this street. In London you either need to wander around and be lucky or have a guide to show you the really interesting places. And if you are going to some of these, you need someone to experience them with.
But how do you go about and find these people, London is a lonely city in that if you talk to anyone you don't know...they are suspicious.

So now, I have 3 days, where I don't know what to do. How do you go about getting new friends, without being introduced to existing friends friends. Isn't that how you extend your circle of friends? Even though I for the most part managed to give off a sense of confidence in public places, I am and have always been shy. I learnt to fake this confidence after having panic attacks when I was younger. But that doesn't mean I am actually confident to go over and say hi to someone...
I have always dealt with my self confidence issues with music. I am ALWAYS plugged into my iPhone. I will always have music on me if I am going to be around on my own, this also doesn't help as people ant likely to actually say hello if I am plugged into my music.
So, I'm basically fucked lol....err...Anyone wanna go for a drink?
