70.6% of young people said that they have seen bullying in their schools while 70.4% of school staff have seen bullying, which 62% witnessed bullying two or more times in the last month, and 41% witness bullying once a week or more (stopbullying.gov). These numbers show that bullying is a big concern that many people might not be aware of it because they only see bullying and are unable to prevent it. 

Also, bullying can happen in any situation such as place, context, and location. According to Smokowski and Kelly, bullying can be considered as the most prevalent form of youth violence and might escalate into extremely serious forms of antisocial behaviour (101). Meanwhile, the victim of bullying which is a youth tends to be more quiet, cautious, and have rather poor communication which makes he/she become abandoned by other youths. 

As a result, the rise of the number of victims, bullying puts a lot of effects on the mental health of the victim: depression, aggressive behaviour, and self-harm. 

The freedom of expression is a value in a democratic society which many of them are not aware of and as a result, it is insulting and hurting someone else's dignity. 

Therefore, the abuse of free expression makes bullying become a common situation, and people do not see what will happen after or the result of bullying. According to Jakarta Post, bullying triggers the intense depression of the victim. For instance, Sulli, a former South Korean singer and actress, was suffering from severe depression. Her death revealed the constant barrage of cyberbullying comments faced by a young artist in the public eyes (Jakarta Post). 

This indicates that the result of bullying is a serious issue that people should be aware of. Moreover, depression of bullying also increases the number of suicide. This risk can be increased further when people are not supported by parents, peers, and schools. Thus, to better understand how media coverage, social media content, entertainment media, and other content about bullying affect the public, more research related to bullying is needed.

Meanwhile, aggressive behaviour might happen through bullying. Bullies often display external behaviours and are hyperactive (Smokowski and Kelly, 104). This indicates negative behaviours are directed toward the external environment which makes the victims unable to control their emotion. 

Furthermore, Smokowski and Kelly stated that bullying occurs at school which makes the victims unwilling or afraid to go to school and might develop psychosomatic symptoms such as headaches or stomach pain when they go to school (104). Other than that, adults who were bullied during their childhood tend to have children who become bullies. 

It shows that children frequently describe their parents as inconsistent which makes them tend to use power assertive techniques with their children in terms of family life (Smokowski and Kelly, 106). Besides, Smokowski and Kelly have found that by age 30, bullies were likely to have more criminal convictions and traffic violations than their less-aggressive peers (107).

Furthermore, bullying also affects self-harming. Self-harm is often a reaction to stress and a coping mechanism to deal with anger or emotions that are difficult to deal with. Based on the anti-bullying alliance, being bullied during childhood will increase the risk of self-harming in adolescence (15). 

For instance, one study found that half of the twelve-year-olds who self-harm had been frequently bullied (anti-bullying alliance, 15). These become triggers for children that can bring up their negative behaviour surrounding self-harming which sometimes are mistaken as attention-seeking behaviour. 

According to Buchanan, studies show that people who self-harm and are admitted to hospital are up to 100 times more likely to kill themselves than the general population. As a result, people felt there was often a lack of understanding about self-harming or the appropriate responses when it comes to being talked to. 

Bullying became a big problem in this world. Many people are being a victim and that needs to be stopped. It causes such a mental health disorder which are depression, aggressive behaviour, and self-harm. 

Knowing this, people should be careful and monitor that bullying is dangerous for mental health as well as the victims. Therefore, people must stop the bully and be aware of the effect that will happen through it. 

Thus, Like Dave Willis, an author said: “show respect even to people who do not deserve it; not as a reflection as their character, but as a reflection of yours.” It shows that people should be respected by others and showing their tolerance that can make life become peaceful.
