Is there a specific reason you seem to want to force yourself to play a game you're not enjoying?
Take a break from it. If you're suffering from "Skyrim Itch", just play an hour and then turn it off.
Memory pattern recognition makes it difficult to play a game because you know where the good stuff is and you're more likely to try and get it rather than immersing yourself into the game for what it is.
Roleplaying is okay, but again, without any true goals, you're just wandering about, and this brings on boredom.
Try setting up some very ridiculous goals for yourself, like playing a character using only an iron dagger wearing fur armor or playing the game but not allowed to enter any major city.
Plenty of ideas, but if none of these appeal to you, I think taking a long break is the best solution to your problem.
