Brian is struggling with himself. He's always been a good student, but lately his grades have been slipping a little bit. He feels like he has nothing in common with those who were once close friends, and yet he doesn't seem to "fit in" with any other crowd. He will be finishing his degree in history next year, but lately he's been wondering whether he really wants to be an historian (and he feels silly that he's wasted so much valuable time on something that he might not even want to do for the rest of his life). His girlfriend wants to get married after graduation, and he had planned to give her a ring over the Christmas break; but lately he's been feeling like marriage should wait; he wants to have time to explore the world and "discover" himself before settling down. Brian seems to have:

identity crisis.

Explanation:

Identify crisis is that period in a persons life full of uncertainty and confusion in which a person's sense of identity becomes insecure, typically due to a change in their expected aims or role in society.

One experiencing an identity crisis, may just be questioning their sense of self or identity. This situation often do occur due to big changes or stressors in life, or it can happen due to factors such as age or advancement from a certain stage (for example, school, work, or childhood).

You can't diagnose identity crisis in the hospital, but it can be detected if one is having any of these feelings;

You’re questioning who you are generally in life or with a certain life aspect such as relationships, age, or career.

You are also having this great personal conflict experience by questioning of who you are or what your role in society is.

A major change just happened which affected your sense of self, such as a divorce.

When your values, spirituality, beliefs, interests, or career path that have a major impact on how you see yourself is a big question in your mind.

You are seeking for more meaning, reason, or passion in your life.

All the things bothering Brian are issues one who is facing or having identity crisis feels.
