How do you turn your brain off?

Going through a break up. Bad one. But, I’ve recognized that I can’t keep thinking about it. Doesn’t help anything, just drives me crazy. I need to get my mind off of it.

How do you shut up your brain when you need to? Booze? Distractions? Lay it on me. I need the help.

Also, how do you juggle these things along with your normal responsibilities? I mean, sleeping all day would be just fine with me, but I have things I’m required to attend to. And I can’t very well be drunk while I do them. I tried that last week, it wasn’t a good idea.
