I have CPTSD. I also have BPD and schizoaffective disorder. In the past week or so I’ve been losing anywhere from 20 mins - 2 days. I just can’t remember anything but a flash or two of what happened. I watched 7 seasons of my comfort show so quickly I’m genuinely confused. 
I also struggle with addiction and drink/use marijuana or D8 every day but I can remember days I’ve used the same amount or more much more easily. Monday and Tuesday of this week are gone. I am someone who has frequent blackouts from alcohol, so that could be affecting my memory. It’s scary af though.
