How should I react to name-calling?

The best way is to not give it a response. Pretend you don't care. Sooner or later the person will quit. Reacting to it only fuels their desire to destabilize you.

Name calling can be very difficult to deal with and it can be very hard to not react. Choosing to react or not react is very personal to you, however I would ask you to consider what you want from the situation. Do you want the name calling to stop? Do you want them to know how you feel? What do you want?

Name calling can evoke a lot of emotion or can trigger stressful emotions that can play on your mind. First thing is to not retaliate as this can make the situation worse. If there is someone you can confide in, tell them immediately.

I have been in your shoes many, many times. It really isn't easy. There are multiple different ways that we can tackle name-calling, such as retorting, ignoring, or telling someone about it. With ignoring it, the person(s) involved may get bored of calling you names and move on to someone else. With retorting, the person(s) involved may become nastier. With telling someone about it, the person told could perhaps put an end to it. There are many ways that we can go about stopping/reacting to this type of bullying. But, it is up to us to decide which one works best. You could try any or even all of the above to see what works best for you.
