Re: My first panic attack confusion
Derealization is a similar term to depersonalization, and the two are often used interchangeably. However, more specifically, derealization is the feeling that 'nothing is real', while depersonalization is the feeling that one is 'detached' from their body or world. Though these feelings can happen to anyone, they are most prominent in panic disorder, depressive disorders and bipolar disorders. So it's important to assess specifically how you are perceiving the events.
The sensation is often associated with panic threshold for those predisposed because there is a corresponding fear that something dreadful is about to take place. The reason that so many persons who experience the phenomenon have difficulty explaining it to precision is that confusion during the events is often co-encountered. This makes it quite difficult to assimilate logical recall such that it makes sense, particularly since something "unreal" would be difficult to effectively describe under any circumstances. Logical thought is based upon the premise of realism.
Because of your age range and posted history of the events, if you notice these symptoms becoming more pronounced or even bizarre and it is accompanied by more gradual predilection for non-social activities and more reclusive behaviors, then my suggestion would be to undergo more formal evaluation for an underlying cause. This is not to say that anything is wrong with you, so take a breath and relax.
