Ah, But Sometimes lyrics

I'm a moody and swirling pool, lost in some dark wood Angry at a million things and more I can do no good Ah, but sometimes - Sometimes i'm a growing blade of grass Washed by the rain, bent by the wind I'm a deeply wounded lonely tree Lost in my own way Brooding on the saddest things and worse I've seen my better day I'm an old and broken tumbleweed Lost on faded sands Dreaming of my yesterdays before I watch the heat waves dance
