It's indeed very difficult to overcome difficulties when you're working on your own. There are resources like [stackoverflow.com](http://stackoverflow.com) and [r/programming](http://www.reddit.com/r/programming) on reddit where you can ask for help, but you're right, it won't compare to having someone there to sit there with you and explain it.

I recommend just moving on to other lessons and resources. You might just be stuck due to the context, and as you progress in other areas and go back, it might become clearer. Don't give up!
