This is how depressed peoples brain works

It’s actually a pattern. See we have trained our brains to think that way. It’s kinda like working out and developing your left arm to pick up all the heavy weight. Then trying to lift things later with your right arm. You’ll find it difficult and natural turn to your left arm. Your brain process things by electrical circuits and paths. And these paths are moldable. You can see this directly in training that produces what people call muscle memory. So in the end, the more we think about the negative, the more we focus on it and the negative memories, the more prone we are to bring them up. It becomes easier and more natural. So then after then after so long we experience the negative effects of this and start trying to change this. We attempt to think of better things positive things. But it’s not natural to us and it’s actually easier for us not to. Overtime we could literally retrain our brains or remold the electrical patterns to turn the way we process and think to be good or positive by default to make it not so, but this is certainly easier said then done. That is a very brutal/hacked look and summary of a very long medical/scientific explanation on things. It was briefly talked about by someone(professional) I knew in passing. They said enough that it got me interested enough to study it out. This was some time ago. It was certainly all logical and convincing. I believe its true and can work. But good luck.
