I totally understand what you're saying. I've been for almost a year feeling apathy caused by an extreme and chronic feeling of boredom I can't seem to get rid of. But, I must say, that routines aren't your friends. Sticking to a routine or any timetable isn't good for you if you're suffering from this, and it won't let you get over this. I tried it myself, tried to keep doing a routine: listening the same songs, going to school, waking up at the same hour, doing the same things, playing the same games, talking with the same people, reading the same... I noticed that, what it only did, is to get rid of my interest for any of these things, decreasing every day I repeated the same routine-activities.

While I didn't find a solution, I did reduce this feeling of boredom, by constantly changing things, and seeking more stimulating activities. If apathy comes, I start singing songs out loud. If I'm reading X book and I'm tired by half the book, I start reading another book. This constantly, and if I get tired of all options left, I get back to the first activity/routine, in an infinite cycle of changes. This has kind of helped me reduce the feeling, but I can't promise you anything.
