I wanted to make sure I remembered.
I used to do exactly what you describe. I went through them often, and one main reason for going over memories that I'd already dealt with is because I had once forgotten them. I was terrified of losing my memories again. I learned a lot of lessons about myself, life, my family, the rapists, society, etc... in those memories. They changed me. AS I SHOULD HAVE BEEN CHANGED, you see? I was required to behave like the rapes didn't happen because my family didn't believe me when I told them. Even now, I pretend like they didn't happen. Most people who know me don't know that I was ever raped. Why would I want them to know that? Still, I feel like by hiding it so well, I might believe my own propaganda... that my life is and has always been easy and uneventful.
Anyway, are you still having new memories?
When I was having new memories still, then they would flood into my mind just as soon as I'd accepted the last one. I was so afraid of what was going to come through next that I would linger on the old ones for some time, trying to catch my breath, trying to mourn them as much as possible. It was overwhelming. My therapist at the time would often call me and cancel our appointments, but I remember thinking about getting a new therapist and I thought "What for? I'm flying through all these memories so fast, I don't have the same issue week to week anyway. I'm going to have to deal with this on my own, and check in with the therapist for a reality check to make sure I'm getting outside feedback." So, that's what I did. I considered what things I wanted to discuss with her the hour before my appointment, and tried to keep things moving forward that way.
Making it end...
I believed that once I understood why it all happened... then the repetitive thinking would end. Not so. Which led me here. I asked myself, "Why am I still obsessing over these memories? I understand them. I forgave myself for my mistakes, and I learned from them. I placed blame where it belongs. I ended my relationship with my family. Why is this still happening, when it is clearly time to move on?"
I found out that I could skip to the end of familiar memories by remembering the resolution that I came to the first 100 times I went over that memory. For instance, I know that my dad is both sad and hurt that I don't speak to him anymore, and that leads me to 90% of my obsessing over the past. I start out feeling like I really, really want to rescue him. How can I save him from this? How can I end this and not destroy myself in the process? And, then my mind goes over memories.... floods me with them, until I see every time that man turned his back on me... as a child AND as an adult. How selfish he was, etc... and that jacks me up, right? I get angry, and I then don't have to try to relieve his pain. BUT, I can skip all that angst, all those memories, being derailed from my own life to try to take care of his... by repeating what I learned from all those memories. My dad chose this for us. He built this wall between us. I cannot take it down, alone. He is in denial, and he lies, so I can't even break through the denial and reach him. I am absolved. I am not an errant adult child.
So, if you've resolved those memories and you're not afraid you will forget them... then, you might try figuring out a few words to bring you quickly to the resolution. I feel relief from the memories without the exhaustion of reliving them, and I get the reinforced awareness of who I am, where I've been, and why I choose not to speak to him. All in a few short sentences.
I hope I didn't say too much, and I hope what I shared is useful to you.
