Is it normal to re-experience memories in your head over and over
I've never had great mental health or sleep, but lately it's taken a nosedive. At my worst, I'll re-experience memories to the point where mentally I am back there, which has led me to do things like get extremely paranoid and hide all my things/lock my door at hearing footsteps in the hall because I am concerned my dad will come in shaking and swinging his fists, or re-experiencing memories of ""conversations"" I had with family over certain phrases. Sometimes, I'll get nightmares or I'll be unable to keep my mind off of past memories, leading them to circle around in my head for hours. I often put off sleeping simply because I don't want to experience any potential nightmares. They aren't usually this bad (certain things still make me very anxious or upset, and I have a lot of self esteem issues for never really fitting up to my parents' idea of being a guy), but they've worsened lately for whatever reason.
