I'm in a semi-similar situation. I'm 23, graduated college a year ago, but I focused on music. I knew some html/css and got a job as a developer and taught myself to code WP themes from scratch. I'm a good graphic designer, but programming interests me more, even though it's harder for me. I recently began using Udacity.com CS101, which is pretty neat. I make the same as you right now, I'm just not sure where to go from here..
