Alone again lyrics

Oh, what have you done
I'm sitting in my room again
And I'm feeling so numb
You left me with a broken heart
And I knew you would run
I'm staring down the barrel of a 44-caliber gun

I'm alone again
I'm alone again

Oh, I can't be wrong
Am I the only one who doesn't feel like they belong
You left me when I couldn't start
So I, I didn't so (?)
I've been sitting around I've been waiting for hours
For far, far too long

All alone again
I'm alone again
