I pretty much feel like this on a regular basis

And sometimes when you're on
You're really fucking on
And your friends they sing along
And they love you
But the lows are so extreme
That the good seems fucking cheap
And it teases you for weeks in its absence
But you'll fight and you'll make it through
You'll fake it if you have to
And you'll show up for work with a smile
And you'll be better
You'll be smarter
More grown up and a better daughter or son
And a real good friend
And you'll be awake
You'll be alert
You'll be positive though it hurts
And you'll laugh and embrace all of your friends
And you'll be a real good listener
You'll be honest
You'll be brave
You'll be handsome and you'll be beautiful
You'll be happy
Your ship may be coming in
You're weak but not giving in
To the cries and the wails of the valley below
Your ship may be coming in
You're weak but not giving in
And you'll fight it you'll go out fighting all of them
