I am the same way. From what I understand this is a combination of emotional numbing and anhedonia. This can arise in multiple disorders but blank mind symptom is most noted in depersonalization disorder.Can someone relate to this? Is it dp/dr?
When I'm looking at an object, I know that I'm seeing it but I just can't "feel" that I'm seeing it, like my brain won't register what I'm seeing. My mind feels blank.
The same is with my thoughts, I can't really "hear" my inner voice.
