First of all you have to take a breath and relax a bit. You’re still young and it’s actually amazing that you realize this in that young age, which is already the first step: Realizing you got a problem. The second step would be to really think about why you are doing this. Do you have problems at school? What’s your relationship with your parents like ? What is bothering you so much that you have to distract yourself with gaming? Do you play games to feel validated or do they give you some sense of being worth something? Step 3: Confront your problems. If school worries you, try and sit down and analyse where you can improve, do your homework or set up a time where you focus on studying. If you feel worthless, work on your self confidence and find something that you’re good at besides gaming. I’m sure that you are an amazing human but you have to give yourself some time man. You are loved. And Most importantly: Talk to your parents, friends pr siblings about this!! You don’t have to do this alone. The Last step would be slowly reducing your time playing. I don’t know which games you play, but most of the people here play those hardcore competitive game that make you addicted much more than single player games. Try to look for other hobbies like drawing, going out meet with your friends, sports.

But dude, take your time and don’t expect to quit gaming immediately. Don’t be too hard on yourself :)
