I need help on a serious situation. I was just visited by police who were told I emailed a teacher saying I intended to harm myself - I did not send that message. I did check my school account and the person indeed sent the message to a bunch of people saying "call me please or I'm going to kill myself". someone is impersonating me, it's connected to a series of threatening emails and messages I've received over the past two months after getting academic help online. He did a lot of my online work.

Another person is threatening me, and saying that the person I paid never paid them and they actually did the work and I owe them. They're going to report me to my school. They keep sending me these messages. What do I do? They have evidence of me with them and payments and also my mother's email and also my address and also my NPI. They are threatening to tell my job too.
