I can easily go into that mode if I'm distressed and I feel like someone is telling me to "stop feeling" a certain way. But I'm not that attached to my feelings otherwise, I mainly view them as something to work with. It's more like "damn, I wish I could stop feeling this way because it's so destructive and I feel crappy...but I can't, I can't, I can't." Being told to stop feeling like that in that situation is no help at all because I desperately want to but it's not just like throwing a switch. It just feels even more frustrating to be told that.
I think that's probably the only time on this forum that anyone has suggested I'm anything other than INFJ. And I can see how it would happen in that situation but that doesn't change the fact that day to day I act much more like an INFJ than an INFP!
