"INFPs feel internal turmoil when they find themselves in situations in which there is conflict between their inner code of ethics and their relationships with others. They feel caught between pleasing others and maintaining their own integrity. Their natural tendency to identify with others, compounded with their self-sacrificial dispositions, tends to leave them confused as to who they really are. Their quiet personalities further feeds their feelings of depersonalization. The INFP's quest for self-identity then seems even more alluring — but increasingly impossible to attain.

As with all NFs, the INFP will feel lost and perplexed at stressful times. As stress builds, INFPs become disconnected from their own personality and perceived place in life. They will lose sight of who they are in relation to time and place. They may not make basic observations, while instead they will focus on the more abstract and symbolic meanings of a particular interaction. This can sometimes baffle those who expect more direct communication and a fairly concrete relationship."

I took a personality test online. Seems accurate enough.
