What is the psychology behind ruminating on negative thoughts?

A common feature of depression or anxiety. Thinking about sad thoughts or worrying almost feels good or addicting. Why is that when it obviously is bad and makes us feel worse?

Basically, we are programmmed to solve problems (problems involve negative thoughts/worrying/stress), it may seem paradoxical, but we even like it, a lot, because it helps us function in our life, it's beneficial for our survival as a species. If we participate in the process and solve the problem (get the desired result), our brains produce hormones that make us feel good and make us want to solve more problems. That's why it feels addicting. We even have more negative thoughts than positive, and remember negative experiences more vividly, because of the reason above (with the exception of traumatic experiences, because it's too overwhelming for a person to handle it properly).  The problem is (pun intended), when it is too much, it becomes anxiety/depression. Hope this helps to clarify it :)
