Both of these are kind of dumb analogies, but maybe they help to illustrate the point.
I sort of see emotions as being like a fish and having someone squirt red food colouring in the water. While the dye affects me, it isn't really a part of me. It takes awhile for the colouring in the water to eventually settle on the bottom and me be able to see clearly again. If I can ask someone I trust how it looks to them, since I'm in the middle of the clouded water and can't see well, they can help me navigate out of it. Once I either get out, or the dye has had time to settle, then I can start thinking about where it came from, how I can keep that from happening in the same way again (or is it just some kind of environmental hazard that I need to learn to work around), what my response should be, whether or not it has a toxic effect or is really fairly benign, etc. It either takes time or someone else's help to help me feel that I am seeing clearly enough to take action. Therefore my first priority is getting the water back to a normal colour or else finding some clean water to move to. After the fact, I'll analyze it till the cows come home.
Or maybe someone turns the radio on full blast. I can't concentrate on what the radio signal is giving me until I can get it turned down to a bearable level or I can get it tuned in more clearly to the channel that will give me the information I need. Offering to analyze the sounds I'm hearing before we get those first things out of the way seems ridiculously unhelpful to me.
I'm curious how it would feel approaching it from the opposite side. I also wonder what it's like for Thinkers who are Fi users. I can't quite get my head around it.
