brutally honest

i am currently having a dabate with myself whether i should be brutally honest here or hedge. i am leaning toward brutally honest. it seems scary! brutally honest means all the details, many of which i have never told. not beacuse i intended to hide them but because i am private and deal with things inside. by the time i speak them thay are resolved in my head so to bring it up again seems unneccessary. however, how can i really tell my story without revealing it?
