You have the right to remain silent.
Anything you type or say will be recorded.
Anything you type or say will be used to manipulate you and may be used against you, not only in a court of law, but also in a myriad of ways you cannot even imagine.
You may be able to delete posts but eradication is difficult if not impossible (http://mashable.com/2014/07/02/how-delete-facebook/#T.8t7Eg6GOqA).
You have the right, nay even the responsibility, to think before typing or saying anything.
You have the right to be compassionate even in the face of taunts and bullying by others (your mother was right, if you can't say something nice about others, don't say anything at all).
You have the right of counsel but an attorney of choice may be expensive.
You are lucky, even blessed, if you have friends you can confide in (in person). The best way to have friends is to be a friend. Remember that they are not bound by the seal of the confessional and even if they appear to be bound, bonds break.
Silence is your safety net. Your family and community are there to support you.
