The Birdwatchers - Understanding Lyrics

Nobody knows just what the future holds
But unmet expectations do get old

I know I'm working all my life away
I'm sacrificing my health to get payed

Done feeling bad?
Oh, what fun you've had!
And though it's coming back
At least it won't come back tomorrow

I've fought the current, well I've tried my best
I'll grab this branch for momentary rest

Oh no, no, no, please don't misunderstand
It's not like I'm not doing all I can

Done feeling bad?
Oh, what fun you've had!
Just know it's coming back
And yes, it's coming back tomorrow
Maybe it's coming back today

I just need some understanding and
I don't need no helping hand from you
I just need some understanding and
I don't need you so get the fuck out of the way
