For me, doomscrolling is a bigger problem than gambling (gambling is not a problem for me at all). On the one hand, I have to stay up to date with current news, but on the other hand, when I look at this fucking hell, at this whole war, at other wars that don't even concern me, I experience severe mental torment. I don't know what dopamine you're talking about. The amount of positive news is small, or at least in the context of major negative events it has little significance.
