The transition out of college into supporting your family sounds daunting, and the games and internet are distractions. I would begin the mornings by doing two things. The first is a gratitude review from the day before — write down three things you have gratitude for as you awake. The second thing is to then write down three things you must do BEFORE you play a game of surf the web. Do these things and then set your timer for ten minutes and let yourself play the game or surf the web.
The process of thinking about something good in your life, having a brief to-do list — then taking a brief break should start to break the cycle you are in. Each time you get to the game and internet part of the cycle your job is to begin again by thinking of something that brings you joy. Think of the people you love, go for a walk, talk to a friend. They disruption of the cycle involves you thinking and doing something positive, having a few goals on your agenda, and then allowing yourself a brief time with the internet and games.
Wishing you patience and peace,
