So I've been playing the guitar for about 8 months. I did it periodically for a while, and I over these past 4 months I've started to take a more serious liking to it. Being self taught, though, I'm having trouble advancing myself in a number of things- such as soloing period, writing songs (I have no idea about music structure), and other various things with my technique.

Could any self-taught players here direct me to a good place to get better?
