How long does a DP episode last for you?

I have a very very mild sense of DP all the time. Otherwise I have episodes. These episodes usually last anywhere from 10 minutes to 2 hours. I'm able to maintain my head enough so as to stop them from going beyond a certain time period. However, it is possible for me to have it severely for an entire day. The intial episode that started this badly for me was 5 days of very severe DP 24/7. I believe I also developed a panic disorder because of this.

The symptoms that I do seem to have 24/7 is a lack of concentration, a slight feeling of being "off balance" and a foggy head.

If im in any introspective state or doing something that would lead me to think more inward the DP is instantly recognizable and intensified. This can be something as simple as looking out a window, staring at a wall, laying down in a quiet room without any distractions. I need to be around my family or other people to make myself feel as if I'm connected, both to them, the world, and the concept of "normality" in general. The less active I am, and I'm generally inactive, the more DPed I feel. Its as if the rest of the world is somewhere else and I occupy a seperate and horrifying space that is away from all that is familiar.
