I might be gone

I might be gone when you get back.
I was thinking I might leave. 
I've been tired for a while now.
So tired

So I might be gone when you get back
I'm telling you so you know
If I'm not here, don't worry
I felt it was time.
It was time.

If I am gone when you get back, 
And I feel I probably will,
Don't be concerned, because as I said
I haven't been feeling the best,
The best

If I am gone when you get back
It's not because you left, 
It's not because of the time you lost my scarf,
Or the fact you forgot the milk again
You forgot again. 
But I don't mind

I going now before you're back
I guess I just thought you should know
That there was nothing you could do to change things
I just, kind of, needed to go.
