hey mark
recently I noticed that you come to school sleepy by playing on the computer I wanted to help you with this addiction because it is a serious disease that is not difficult to cure as you want I can help you with this addiction it will be simple to spend less time set yourself a limit for example to 22/24 at night but this is the maximum hour at which you have to go to bed. as you continue to sit in front of the computer, you will have thoughts of killing, for example.
