At first, the nurse uses the fentanyl at work.

She takes vials from storage and injects herself in the bathroom.

Then she starts taking the vials home, a 30-minute drive to a Connecticut town and a more rural

part of the state.

This is where she's raising her children, three of them.

It's a wealthy town, but not hedge fund wealth.

Kids go to public school and play little league.

For a while, the nurse taught catechism at the church.

The nurse is divorced from her children's father, who, according to court documents, is

a volatile presence in their lives.

The tooth fairy will be coming a lot, because I'm going to knock your teeth out, and maybe

the ambulance will have to come, because your jaw bones will break.

As an example of the kind of thing the nurse claims the father has said,

according to a police report, the father denies making this in all such threatening statements.

But the children have said they are scared of him.

The nurse is scared when they are with him.

The nurse sees herself as the stable parent.

That is who she needs to be.

But now she is doing this thing, this thing that she needs.

In fact, she needs it to remain stable.

Sometimes she tries to stop, but she can't.

She can go for a couple days without using.
