Who is going to jump on your back for gaming it up, in this day and age? I think there is a huge percentage of gamers on the planet now, so I don't think you're alone. Nor do I think you should feel bad about it. Everything in moderation. If stress is your true addiction than becoming addicted to an uplifting and relaxing game is probably what you need for balance right now.
If you're stressing about not stressing because you are playing videogames than you are still forcing your mind into anxiety.
You are beating yourself up girl. Does it feel good? Cause you keep doing it for too long you will beat yourself to death.
Breath and let go.
Good things will enter your life.
