Many young adults change goals and desires constantly, and even have a difference sense of self at times. However, when you combine constant changes in goals, identity, career plans, jobs, values, morals, friendships and relationships with extreme emotional changes that can lead to unusual amounts of behavior and personality, you might be experiencing borderline personality disorder, according to the National Institute of Mental Health’s website.
Other symptoms of borderline personality disorder include aggression, self-injury, alcohol and drug abuse, an inaccurate sense of self and thinking, and low self-esteem and self-worth, according to the website. People with borderline personality disorder might not know who they really are and feel bored, empty and misunderstood.
These symptoms and constant changes in behavior and personality can affect social relationships as well, leading to instability in this area of life as well.
