I agree with NancyLebovitz about not focusing on your IQ. You story and actions show that you are more than intelligent enough to get along doing whatever! Your curiosity, and willingness to do things (like move to a different country) in pursuit of your goals are way more important than having to read things a couple times to understand them.

Friendly advice- Try breaking long chunks of texts into much smaller paragraphs. It makes reading your story (and it's a very interesting story that deserves to be read!) much easier. If you don't feel like figuring out where natural paragraph breaks are, then just go through and put one every couple sentences!

It sounds like you're in DC. They have a pretty active LW group, afaict. If you haven't yet, you might want to join their google group here.
