How come you suddenly want to become a programmer? Just for scripting games or are you actually interested in getting deeper into it, perhaps even as a career? If it's just games, you can learn it pretty quickly, a couple of months maybe, even though it will seem impossible at first.
I've been working as a professional software developer for 13 years across different companies, so I got to know a lot of programmers. Don't worry, most of them are creatures very much like you. If you really want to, I believe you can do it too!
