you learn to accept the fact that everyone mentally disordered or not has holes in their memories. as human beings our brains dont store every ounce of everything we go through. it stores those things that are important to us at the time they happen. everyone has things about their life they dont remember. for some its their childhood, for others its not so severe but everyone has holes in their memories even normal people who have a life that is perfect to them. you learn to accept its normal to not remember things traumatic or not in your life. and that enables you to move on.
