INFJ personality types and INFP personality types are two of the MBTI personality types that tend to struggle with unhappiness in life. For INFJ personality types and INFP personality types, this unhappiness usually stems from keeping themselves small. This can show up in the workplace, in family life, or in a friend group. INFJ personality types and INFP personality types usually play small to protect themselves, and to ensure that they don’t trigger insecurity in others. However, this has a long-term detrimental affect on the INFJ or INFP, as they don’t feel like they can ever really be seen, heard, or acknowledged for who they are.
