I know that you are addicted to the internet and I am writing to you to stop your addiction and to let you learn more about the cyberwellness.
Being addicted to internet is a bad thing, there have been many cases of people addicted to the internet, and end up committing suicide or other horrible outcomes. You will neglect your schoolwork and your grades will deteriorate and your eyesight will worsen.
You should go outside, exercise and do outdoor activities or spend some time with family and friends. If need my help, I can remind to take breaks after spending hours on the computer.
