I had that same problem with a levelling of skills and more importantly, a levelling of inspiration at about the same stage.
I was stuck too because most people I knew where into folk music (which is ok, I don't dislike folk music). A work colleague asked me along to the Irish Club for their jam sessions. It proved that musicians across all genres have one thing in common, the love of music.
I reckon all the advice posted is very good and has been advised to me at some point even though I still miss the odd barre chord here and there.
Try penning your own stuff. I put together some rubbish songs on scrap paper and then they get buried in the top draw somewhere, but it chnaged the thought process a bit, then reality takes over and it's back to the office.
Good luck and keep at it, it'll come together quiet nicely.
