Is this anxiety?

[colinsmom]

I have been off for the last few weeks. It is not really a dizzy feeling it is like my reaction time is slow. Is this what everyone calls derealization?

Could you be more specific? Derealization I believe means that it feels like you have a psuedo out-of-body experience ( I could be wrong), like you are there and not. If by slow reaction time you mean slow reflexes, this can be due to fatigue, especially if you are prone to anxiety. Even aging starts to wear on reaction time.

Also, reaction time to what? Details and circumstances are important because someone may be able to relate to that situation. Reaction time is not exactly standard jargon. Are you talking about playing sports? Feeling slow? Eyes not catching details like they used to? Your reflexes? What happened to make you suspsect that your reaction time has lowered? Can you describe your feelings in detail, or do you have a more professional definition, so we can better help you?
