Indeed. I didn't think myself into DR, and neither can I think myself out of it.Some people are likely to have DP than others, possibly for genetic reasons. That would effect whether or not you can "think yourself," into having the condition. I personally believe chronic DP is a serious condition, and that some underlying problem must at least trigger it. You can't think yourself into having schizophrenia or bipolar disorder, and I think clinical depression also has more factors to it than just thoughts.
