The charity Young Minds has some great mental health support information on their website for parents and young people who may be dealing with issues around anger or aggression.
They say that Anger is one of a range of emotions that we all experience and it’s ok and perfectly normal to feel angry about things that you have experienced. Anger can start to become a problem when you express it through unhelpful or destructive behaviour – either towards yourself or other people.
It can also contribute to developing mental health problems, like depression and anxiety, or worsen existing problems.
If you are seeing worrying signs with a young person in your family, then it’s important to seek guidance and support at an early stage to avoid the problem escalating.
