Sigh-FYI

Disassociation is a huge part of living with anxiety. It's possibly the scariest part of anxiety and the toughest portion to overcome.
Derealization is a portion of disassociation in which you feel like the world isn't real and you're watching a movie. It's almost like a Twilight Zone episode where you think you're in a real town but in the end you're actually on a movie set. It feels like you're positive the world is fake and the colors and images are about to melt away to show what's really there. Which of course never happens. When the derealization feeling comes about it's common to try to focus on one thing and not look around, which causes for much more of a panic and disconnect. Usually when I feel like this, I step outside and get a really good look at everything around me. A 360 view of where I am will snap me out and reveal that everything is real and touchable.
Depersonalization is another portion of disassociation in which you feel that you're not in touch with your body or like you're a passenger in the car that is your life. For myself, this happens to me while I am having panic attacks. It's as if part of me is looking at myself and thinking "Really? What're you panicking about, there's literally nothing going on." While the other more powerful part of me is having the actual attack. It's hard. Especially, when there's people as sensible as your later self telling you, "Tell yourself everything is fine." When I'm like, "Thanks. FYI, Half of me already knows that. I just need the other half to cooperate."
It sounds scary, and it is. However, it's also kind of interesting. You have to ask yourself sometimes, "How do people come up with this stuff?" when you watch psychological thrilling TV shows or movies. I bet your bottom dollar that someone has probably really experienced it. The upside to disassociation if any, would probably be the creative and unique perspective you suddenly have on life, that almost seems Sci-fi to everyone else.
