coming clean: need help

[painful paradice]

so i was going to tell them a while ago, but i never got around to it, and now this happened:
i forgot it was Wednesday, Wednesdays after school i have therapy and I forgot because my mind has been slipping so much, and my grandmother picked me up for therapy. I wore a short sleeve shirt that day, and the sleeves ride up on it for some reason
but anyways
my therapist saw my scars peaking out from under my sleeve at the top of my arm. she got worried it would get infected, not that there was any open ones or anything i haven't done anything deeper than bare skin in a while
again getting off track
so she told my grandmother. turns out she already knows and really couldn't care less apparently
so finally getting down to my point.
they already know, should i just go ahead and admit it. when she asked i denied it forthwith.
i just can't open my mouth and admit it though. i mean she actually saw every one of the scars and touched them and whatnot, something i've never allowed anyone to do, barely even myself. but i can't open my mouth and say that one word "yes."

If you are talking about admitting it to your therapist, then I would try to do so.
He/she is there to help you, not to judge. Once you admit to yourself, and someone else, that there is a problem, it becomes easier to deal with it. You are aware that there are other people who care about you, so you don't have to forever live in fear and secrecy.

Maybe you could wait to she if your therapist brings it up, and if she doesn't, and you feel you can, then go ahead.
