Why It's Harder To Learn Spanish In Spain

So I have been in Madrid for two weeks now, and I finally feel as if I'm settling in.  Nice to know I am finally comfortable, halfway through my trip.  That being said, one thing I think I have learned in my time here is that, for me at least, practicing Spanish has actually been harder and even less productive than when I am home in the U.S.  "How can that be?" you ask.  Well, let me try to explain.

First of all, I arrived in Spain on a Friday morning and I hit the ground running.  I was excited, terrified, and exhausted all at once.  I had never been to a foreign country, and to be honest, even my experiences in big cities in the U.S. were limited, so to find myself on a subway, chugging away under the streets of Madrid all by myself was exhilarating and terrifying all at once.  I found my way to my host's apartment, unpacked, and hit the streets, hoping every stranger on the street would stop to chat.  Well, that wasn't the case.  In fact, I was nervous to be walking around all alone.  I didn't know anything or anyone and I wasn't even sure I could find my way back to the apartment if I strayed too far.  My first few days here were a blur and once my vision cleared, I realized not only had I not spoken very much Spanish, I hadn't spoken much at all.

After getting myself quite lost one afternoon, I decided I had better head home, regroup, and plan things out a little better.  I realized I had locked myself into a defensive mindset.  I was constantly on edge, worried I would get lost or say or do the wrong thing.  Instinctively, my brain locked me into English.  I wasn't consciously aware of it, but I wasn't allowing myself to think in Spanish.  I think I have said it before, but for me, speaking in Spanish is like flipping a switch in my brain.  Sometimes it is very easy to switch between languages, and other times, it takes quite a bit of effort.  Since I realized the trouble I was having, the switch has been easier to flip, but I am still reverting to English too quickly.

I have two more weeks here and I am hoping I can be more diligent in thinking and then speaking in Spanish.  I know I can do it, but it has to be done consciously.  I know being out of my comfort zone has had an impact on my abilities and I am hopeful when I return to the U.S. I'll be more comfortable using the language.  We'll see. Do you think stress plays a significant role in our language learning?  I think I would have to say yes to that.  Thoughts or comments?
