awww hunni u have a predicament!!! i hated that too. but if u tell them, they will b happy that u can open up to them. they will try to get u to stop. if u dont, they may find out by accident. if u dont want to give it up just yet, u can talk to all of us. be it PM chat or posts. we will support u and u can always talk ok?
i would recommend telling your teacher or councillor but they may not no the best way to go about it. councillor probably will.
they will hurt less if u tell them. and it is better that they hurt a lil than u hurting alot coz u cant cope with all the pain, u cant be expected to do that
take care
