I have some good memories. I remember being happy on some camping trips. My mom had to hold it together because things were less private on trips. There are memories that I used to remember as good, but most of those are covered in awful feelings--like they weren't really good at all, just all I had at the time.
One of my littles said something very good to me though. He said, "My life now is so much better!" I had been talking to my t about bad memories, lamenting over how many are painful- and this little one wanted to say he has good memories now. Rather, he has new experiences of good things that kids are supposed to do, like coloring and playing with toys and eating candy and the like. Before he came forward he was locked in trauma and had not one single good or child-typical experience. He doesn't like me to dwell on how bad things were because they are better now. Sometimes I think he has a quicker grasp of reality than me.
