When you aren't able to speak to or spend as much time with someone you care about as you'd perhaps like to, you sometimes start imagining things that the other one is getting up to. This can get out of control and end start a whole life of its own which can drive you into the ground. This song was written for someone who felt this way about me. As much as I tried to reassure her everything was ok, she still wouldn't listen. This was the only way I thought I could get through.
