Having depersonalization ? i had a panic attack from getting really high for my first time ever. i feel zoned out 2 weeks later but what is this ?

It's not clear: Exactly what is happening. What drug did you use to get high? Some have after effects. Consider meeting with a therapist and discussing what has been happening. Good luck and let us know how it goes.

Panic attack: Depends on what you got high on? It can damage the area of the brain that produces emotions and panic attacks usually in connection to other areas of the brain stem. If the damage is permanent a general rule of thumb is that brain cell do not reproduce although there is some data to suggest otherwise. Avoid drugs, and get a brain scan to see if something can be located.
