hi, i was wondering if anyone could relate or had any answers! sometimes i have large gaps of memory loss. like, i can’t remember what happened in certain parts of childhood at all. but other times, i can remember everything, including things I remember previously not being able to recall at all. as if the lack of memory didn’t exist. does anyone know what that’s called? thank you so much! sorry if this sounds confusing.
