I live with a son who is mentally ill. I love my son. But he terrifies me.

A few weeks ago, Michael pulled a knife and threatened to kill me and then himself after I asked him to return his overdue library books. His 7 and 9 year old siblings knew the safety plan—they ran to the car and locked the doors before I even asked them to. I managed to get the knife from Michael, then methodically collected all the sharp objects in the house into a single Tupperware container that now travels with me. Through it all, he continued to scream insults at me and threaten to kill or hurt me.

That conflict ended with three burly police officers and a paramedic wrestling my son onto a gurney for an expensive ambulance ride to the local emergency room. The mental hospital didn’t have any beds that day, and Michael calmed down nicely in the ER, so they sent us home with a prescription for Zyprexa and a follow-up visit with a local pediatric psychiatrist.

“I’m going to kill myself,” he said. “I’m going to jump out of this car right now and kill myself.”

That was it. After the knife incident, I told him that if he ever said those words again, I would take him straight to the mental hospital, no ifs, ands, or buts.

I pulled up in front of the hospital, frantically waiving for one of the clinicians who happened to be standing outside. “Call the police,” I said. “Hurry.”

Michael was in a full-blown fit by then, screaming and hitting. I hugged him close so he couldn’t escape from the car. He bit me several times and repeatedly jabbed his elbows into my rib cage. I’m still stronger than he is, but I won’t be for much longer.

I am sharing this story because I am Adam Lanza’s mother. I am Dylan Klebold’s and Eric Harris’s mother. I am James Holmes’s mother. I am Jared Loughner’s mother. I am Seung-Hui Cho’s mother. And these boys—and their mothers—need help. In the wake of another horrific national tragedy, it’s easy to talk about guns. But it’s time to talk about mental illness.
