Dealing with these sort behavior from a teenager is often quite challenging. You really got to take a step back and start to see things as objectively as possible. Adolescent issues should be seen as multifaceted and more as a systemic problem than an individual's problem. It is likely that these behavior has developed over many years due to interplay of multiple factors like environment, experiences, upbringing, genes, personality factors like confidence, self esteem etc. Adolescent years are further complicated because of the transitions and changes one goes through in body, hormones, emotional, identity, social and interpersonal issues.
