How to unfuck my life?

Me 18M, life is great. I go to gym 5-6 times a week, make around 70-100k per month, height above 6 ft, body is kinda nice too, single and working on myself, but the problem is I am kinda addicted to mobile. Can’t take off my eyes from it.

I use laptop when i charge my phone and my screen time is like 16-18 hours. Also, my concentration power has really got weak and I can’t really remember things as I used to. Do you guys have any solutions for it?
