I'll throw in another vote that it's about depression and suicidal thinking. I've always thought it's pretty clear. He's sick of the pointlessness of life, he's awake at 4:30am saying "it doesn't get much worse than this," he stays at home because he's too depressed. He's thinking about killing himself ("gonna get me a little oblivion") but he's ambivalent about it ("keep myself away from me.") Like monkeybear pointed out, I am sure a lot of people who have experienced depression understand the ambivalence of suicidal feelings and the idea that you want to keep yourself safe from your own suicidal impulses.
