Johanna Warren past tense

I went away for months, or maybe it was years
My house was overrun by fears
But while I was not home
I left a faucet running
And I won't call it hope
But I'm still alive, so that's something
One thing I learned after so many months or years
Regret is the past tense of fear
And I know memories
Are like running water
And I don't want them to freeze
But I could use something to hold on to
Strange faces in the crowd
And you walk around like you own this town
In my kaleidoscope heart
You're a shard of fire
And I won't call it love
But there's more to it than desire
