it's hard to forget a bad memory

people always said...'let gone by gone' 'just ignore' 'don't think about it anymore'
'what past it just past' 'open a new diary' 'just act like nothing happen'
but aren't they noticed that it's not easy as A - B - C.,
even we try to busy our self in one all day.,before sleep we still think about it for a while.,even for a minute or a few seconds.,we try to let it go..but deep inside our heart and brain.,it's still keep running inside.,
we can't avoid it.,unless we found something to replace it..yup !!! REPLACE IT!
but... I'm not found it yet..huhuuu =((((((
