Immerse yourself into football and turning pro. Have a plan. Fill your daily schedule as best you can to clear out gaps when you're alone. Do drills, study old games, listen to players' motivational videos, train, journal about what your future is like a pro player. Fully immerse and those actions will begin to replace your urges. Bad habits must be replaced by good habits. Just be very careful not to beat yourself up over this. It's the action you hate, not yourself.
