There are some things you can try that could make a difference to your family life:
Go to your GP if there is a worry that your child has ADHD. A diagnosis may help you to move forwards.
Talk to the rest of your family to make sure they understand what is going on, so you are all on the same page.
Set some boundaries and don’t put up with bad behaviour e.g., swearing.
Ensure you help your child have a healthy lifestyle including a balanced diet, exercise and a sleep routine.
Lastly, find out about local parenting support groups to interact with other parents going through the same thing. You can help each other.
