A Curse?

I have this tendency where I intend on laying my head down for a while and I find myself being grasped by my own thoughts. They pull me in, and an hour goes by and sometimes two. This happens also when I just sit somewhere comfortably. I don't realize that I just sit so still like a statue just thinking until someone shakes me or I snap out of it myself. I figure that 80% of my daily activities consists of thinking. I often wonder if I'm the only one who experiences these weird spells. I know that Greg doesn't really understand them because he doesn't see the sense in sitting for so long. He needs to get up and get things done. But I don't think I do this because I don't want to get things done. It's just something that I do. Probably something worry warts do. My thoughts usually are about the future, my regrets, my goals, my fears, something that I am upset about, something that I wish for in someone, or things that have changed. And because I think so much, I have this crazy belief that if someone else doesn't do this, then they must not care about me or about anything. It's a ridiculous idea, but I still half believe it.
