I recommend taking a look at this video. Some will love it and some will hate it, but everyone can learn that "DP" is not a chemical imbalance or a broken brain. The name "depersonalization" is ironically very close to the truth, but represents a complete lack of understanding about a very natural human experience, one that unfortunately is barely recognized in the West, though it's been known about and sought after for thousands of years in other parts of the world. I wish I'd had this knowledge 20 years ago. It would have saved me from a great deal of suffering.
