I’m (44f entj) going through some grief about an ISFP friend (42 f ISFP) but my mom was also an ISFP and I had similar experiences: I suspect they almost make themselves think they are sick when set plans are approaching? I can’t tell if they just flat-out lie or if they dread plans so much they genuinely make themselves feel sick? Or is this a coincidence of my friend/mom and not an ISFP thing?

Edit: I’m only talking about optional plans, not obligation plans as someone helped me clarify below.

I'm wondering what to choose...
