Let's get things straight here. It's not that bad. You have good days and bad days, but as I might have said earlier, the good days just aren't that interesting, and also it's a bit more difficult to protect the innocent on the good days as names get bandied around.
The bad days are so much easier to write about. Everyone loves a tortured artist. The Verve on drugs - brilliant. The Verve without drugs - bad. Radiohead full of angst - brilliant. Radiohead loving their children - rubbish. Ryan Adams fucked up on drugs and in a pit of heartbreak - wonderful. Ryan Adams sober - a bit dull (sorry). And it's all about venting; you have to get it out when you're upset. When you're happy you want to savour it and keep it for yourself.
Also if you tell people you're happy, they think you're smug. If you tell them you're depressed, there's a good chance they'll think you're edgy.
