Whatever it is, it will pass. That's as close to wisdom or good advice as I'm likely to offer. But it's true.
I don't mean that it's nothing - I know it isn't. Or that it'll be easy to get through - it probably won't be.
Even so. The future is bright. Believe it. Make it so.
And like ED said - Iron helps. I also agree with Henry Rollins:
"The Iron never lies to you. You can walk outside and listen to all kinds of talk, get told that you're a god or a total bastard. The Iron will always kick you the real deal. The Iron is the great reference point, the all-knowing perspective giver. Always there like a beacon in the pitch black. I have found the Iron to be my greatest friend. It never freaks out on me, never runs. Friends may come and go. But two hundred pounds is always two hundred pounds."
