i have been diagnosed with bpd and my psychologist thinks i have c-ptsd. i am constantly dissociated and struggling with derealization/depersonalization. i constantly come to and don’t know where i am, or if i’ve gone too far on the bus, etc. i used to walk to a random floor of my apartment building and not know how i got there. my partner is worried i have a dissociative disorder because it’s truthfully nonstop. like to the point today my coworker told me i constantly seemed upset or distracted and constantly annoyed and i had to tell her i’m constantly dissociated so she didn’t think i hated her or my job. my psychiatrist doesn’t want to pursue more diagnoses until my bpd is more under control (i’ve already done six months of dbt) but i don’t know if i’m dissociating because of my bpd or because of something else. i had a very traumatic childhood and i honestly don’t remember much before i was 19 and moved myself across the country to get away. how do i know whether it’s part of a disorder i already have, or if it’s something else?
