Action is the way out of SA. If you don't take action - read: be social - you're going to get into overthinking whether you like it, or want it, or not. The emotional brain has to occupy itself with something right?
I have a very telling example of the necessity of action. Take a look...
I went to Tokyo last summer. The first week was HELL - english is scary to use for me, so ddin't really say much; I was there with the people in my friend's band (one of very few friends I have and I really didn't know the others).
So, it was fucked for a while... Why? Because I was with them all the time. Really. Not because it was a "scary new country" or anything like that. I have always had a strange vibe with these people, and have a very strong association to that vibe - with them. It's like a forced that sucks me in.
But I stayed... And. BOOM... last two weeks I talked to 200 people. How did I do it? One shift, I think. The band started doing shows (9 in 11 days) in the last two weeks - and before, sometimes, during and after those shows I talked to people in the venues. Ok, these are japanese people, so they're "nerdy" - but that's not what this is about at all. It's not about being cool - you're cool if you see the cool in others right.. So I just talked to people. Started small, but... isn't it amazing that cutting off from the familiar can be what saves you from being afraid? I think so at least.
You can learn two things from this I think: 1. that you never know what will happen tomorrow. 2. and that if you keep slugging it might work out, however bad it looked, literally, yesterday. So... hope you got anything out of this! I am interested in helping people out with these problems, and have a place where I have written stuff. take a look
here it is spam there are also more hubs like these, four more, that you can check out. I've been into psychology for a long time - mostly to fix myself, really - so I know what I'm talking about. Take a look. There's also an e-book there that's great that I've used myself.
