So, I was wondering. I have an ISFJ brother and it seems like he does a lot of spiral thinking. It seems as if he's always thinking about all the possible things that can go wrong and happen to him. Does this happen to other ISFJs? And if so, is there a way to comfort him? He doesn't tell me when things are upsetting him, even though I know he's upset. I'm not really sure what to do when he gets in his negative mode. Do other ISFJs do this? or is it a guy thing that he doesn't want to talk to me about it?
