I went through something with T where I made a timeline of memories. At first it was all bad stuff, but after a while there was stuff that was good (or at the very least, not bad)--things like a school field trip, or going to see a movie with a friend's family. When I put those into the timeline I could see that my life was more than just the bad stuff I remembered so often. There was other stuff, too. I am more than the bad stuff that happened.

I found that when I was remembering, the good stuff floated in slowly--but the more not-bad stuff I remembered, the more "good" memories they triggered. So be patient with yourself. What needs to come will come.
