If you feel that the only way to save yourself is to runaway from everything, then do it. It's not wrong if you choose yourself above else. Do what you think is right because the only one who can understand you better is yourself. It is never wrong to turn your back away from everything, choose yourself for the meantime. Because trying to fix everything while slowly breaking yourself will cause you no good. Pick yourself, gather your strength and when you are ready, stand straight and retrace your steps back. Don't rush everything trying to fix your problems right away, it's okay to take your time and leave it for the mean time. Comeback when you are ready and you have your enough amount of energy.
