After much research, I have realized that I have depersonalization disorder, also known as depersonalization/derealization disorder (DPDR).
DPDR is a form of dissociation, which can be triggered at times of high stress/anxiety.
In the following video I share information about DPDR and talk about my specific symptoms.
I filmed parts of this video on different days, the final portion was done today.
Here is the wikipedia link I read from in the video.
I hope you find this information helpful and I hope it helps you discover new ways to aid you on the path of recovery from CPTSD, or whatever the cause is of your DPDR.
