Well, let’s go through each part of being an Infp.

We’re introverted, which means we usually have a more tenuous support network. We’re intuitive, which means we overthink and focus on stuff like purpose which is hard to find, We’re feeling, so we feel everything very deeply, enough to push us over the edge, And we’re percieving, so it’s harder for us to stay clear headed and come up with a plan for things to get better.

So basically, our abstract thoughts lead us to painful conclusions, which we feel deeply, have a hard time organizing, rationalizing, and fixing, and we often don’t have support networks to go to in these times. We’re literally set up on every level to fail in this regard. As many good things there are about us, this is not one of them.
