It's so easy to slip back into old habits. So very easy. To return to exactly what you wanted to run away from.
Habits are comfortable, which us why they're so difficult to get rid of. But even the uncomfortable ones which brought you pain and sorrow and discomfort, even those which you know are bad for you, those are difficult to leave behind too.
You run away from them, and you decide you want happiness elsewhere, but it doesn't last long.
Because some habits seep into your blood. And no matter how far you run, how much you try, those will never go away. And you will slip up, fall off the wagon. And hate yourself for it. Powerless against it.
Because some habits are here to stay. Especially the ones that do you no good.
