Why signs are easy to miss
Cyberbullying happens on phones, tablets and consoles, often out of sight of adults. A young person may be targeted through group chats, comments, game lobbies or fake accounts, and many do not tell anyone. Common reasons include embarrassment, fear of losing their devices, worry about making things worse, or doubt that adults will understand.
No single sign proves bullying is happening. Moods change for many reasons, particularly in the teen years. What tends to matter is a noticeable change from the young person’s usual self, lasting more than a few days, especially if it is linked to being online.
Changes in how they use devices
Some patterns may be connected to online bullying:
- Seeming upset, tense or angry during or after using a phone or computer
- Hiding the screen, turning the device over or closing apps when you approach
- Suddenly avoiding devices they used to enjoy, or becoming unusually attached to them
- Deleting accounts, creating new ones, or changing usernames repeatedly
- Staying up late online or being distressed by notifications
- Checking messages constantly and looking anxious about what they might find
Opposite behavior can appear too. One child may stop using devices altogether, while another cannot put them down. Avoid reading too much into either.
Emotional and behavioral changes
Bullying can show up in everyday life as:
- Becoming withdrawn, quiet or tearful
- Irritability, sudden anger or mood swings
- Losing interest in hobbies, friends or activities
- Reluctance to go to school or social events
- Changes in sleep, such as trouble falling asleep or frequent tiredness
- Changes in appetite
- Headaches or stomach aches with no clear cause
- A drop in schoolwork or concentration
- Lower confidence, or talking negatively about themselves
These signs can have many causes unrelated to bullying, including stress, friendship conflicts or health issues. Treat them as a prompt to start a conversation, not as a diagnosis. If you are worried about a child’s mental health, a doctor, school counselor or other qualified professional can offer proper guidance. Our discussion of social media mental health explains how time online can influence mood in both positive and negative ways.
Signs in friendships and social life
Pay attention to changes among peers. A young person might suddenly lose friends, be left out of group chats, or avoid people they previously spent time with. They may mention a former friend in a tense or fearful way, or become secretive about who they are talking to. Alternatively, they may seem anxious about being excluded, which can be linked to a fear of missing out as well as to deliberate exclusion.
Warning signs that need urgent attention
Some signs call for immediate action and professional support. If a young person talks about wanting to hurt themselves, says they feel hopeless, or you believe they might be in danger, stay with them and contact your local emergency services or a crisis line in your country right away. If threats of violence are involved, contact your local police. You do not need to wait for proof.
How to start the conversation
How you respond in the first few minutes can influence whether a young person confides in you again. A few approaches tend to help.
Choose a calm moment
Pick a time that is private and unhurried, perhaps during a walk, a car ride or a shared meal, rather than right after you notice something upsetting. Side-by-side activities are often easier than face-to-face questioning.
Ask open questions
Try “I have noticed you seem down lately, and I wanted to check in” instead of “Who is bullying you?” Let them speak without interrupting. If they say nothing is wrong, you can say you are there whenever they want to talk, then return to it later. Broader tips on this are in our piece on teen conversations.
Listen and reassure
Tell them they are not to blame, that you are glad they told you, and that you will decide the next steps together. Avoid reacting with anger, minimizing it with “just ignore it,” or threatening to take away their devices. Fear of losing access is one of the main reasons young people stay silent.
Practical steps once you know
Once a young person has told you what is happening, you can work through a few steps together:
- Save evidence such as screenshots with names, dates and messages before anything is deleted.
- Use block, mute and privacy tools on the relevant apps, and review their privacy settings together.
- Report the content or account to the platform.
- Tell the school if other students are involved. Most schools have anti-bullying procedures and a named contact.
- Avoid contacting the other young person’s family in anger; go through the school or a calm, planned conversation.
- Contact the police if there are threats, blackmail, stalking or sharing of private images.
Let the young person have a say in what happens next, so they feel supported and not sidelined.
Keeping an eye on things afterward
Check in regularly over the following weeks, because bullying can continue through new accounts or move to other platforms. Encourage friendships and activities offline, and make sure they know they can come to you without punishment. If distress continues, a school counselor, family doctor or other qualified professional can help.
Young people also benefit from knowing what to do if they see bullying happen to others, and from understanding that everyone deserves respect online. Families sometimes find it helpful to agree on household expectations together, which are easier to follow when the young person helped create them.
