Just going to throw in a sympathetic nod. We had a loss of focus around the same age, too (and we homeschool, so it wasn't the middle school social scene!). No romantic interests, no social posturing, just trying to figure oneself out, and negotiating generally bigger, adolescent emotions, and shifts in relations with parents. It lasted about 6-9 months, and then kind of sorted itself out. No illusions that this is the end of adolescent angst, but that particular wave seems to be past.
