Wow. I have felt like that for a long time, and it's a little reassuring to hear that other people feel that way, too. I hate the depersonalization feelings. I get caught up in them. It's like I'm watching myself from outside. I get this dizzy feeling, and I have to do something to bring myself back to my body. I spoke to a doctor about this years ago, and he said to try to explore the feelings when they were happening, instead of trying to get back to reality immediately. I've tried to do that, but it doesn't really seem to do much for me. It's a scary experience and my first reaction (once I've tortured myself with those thoughts for long enough) is to distract myself until I feel better!
