If you're even a little bit selective with your reading list you can still be learning a lot from it. Bonus points you get to but into litfag discussions.
Also consider doing something creative, like writing or art. You'd be surprised how much better you'll feel when you give yourself a constructive release valve for those pent up creative energies.
