Typically, for a misdemeanor complaint, the complainant can ask that charges be dropped.Quoting Rockyj
I suggest, particularly given the effect of this matter on you, that you consult a local lawyer before sending any letters. A lawyer should be able to advise you as to whether any alternative sentences are available which might help you avoid a conviction. You should also consider seeking mental health care, to help ensure that this doesn't happen again.Quoting Rockyj
