Nothing will haunt you more than your inner fears, bad memories, insecurities, burden of your sins, whirls of thoughts and vacant spaces in your soul. You can never let these go.
If you try to fight with them you will lose everytime. If you try to throw them away , you will fail. If you try to ignore them they will eat you up alive.
The only way to better survival is to adapt by acknowledging their existence in you. Then one day you will thank these ghosts for making you learn the lessons of courage, strength and survival.
