"Mom," I'd say, and she wouldn't respond, so I'd say it again. Sometimes it took three times before she'd slowly begin to turn her head, but when she did I would suddenly feel scared, like I didn't want to see her face after all. Like in those few moments, she might have changed again, shifting deeper into someone I didn't recognize.

My sisters remembered this time better than I did, as they were older and therefore privy to more information. And in typical fashion, they each had their own way of dealing with it. It fell to Kirsten to take care of things around the house, like cleaning and making our lunches, when my mom wasn't up to it, which she did with her usual bravado, as if nothing was wrong at all. Whitney, on the other hand, I often found outside my mother's half-closed bedroom door, listening or peering in, but she'd always move on when I saw her, not meeting my eyes. As the youngest, I wasn't sure how to react, other than to just try not to make trouble or ask too many questions.

My mother's condition quickly grew to dictate our lives. It was the barometer by which we judged everything. In my mind, it all came down to the first glimpse I had of her each morning. If she was up and dressed at a decent hour and making breakfast, things would be okay. But if she wasn't and I found my dad in the kitchen instead, doing his best with cold cereal and toast, or even worse, if neither of them was in sight, I knew it was not going to be a good day. Maybe it was a rudimentary system, but it worked, more or less. And it wasn't like I had a lot else to go on.

"Your mother isn't feeling well," was all my dad would say when we asked after her as we sat around the dining-room table, my mother's place glaringly empty, or when she didn't emerge from her room all day, the only view of her a lump under the covers, barely visible in a sliver of light from the drawn shades. "We all just need to do the best we can to make things easy for her until she feels better. Okay?"

I remember nodding, and seeing my sisters doing the same. But how to do this was another thing entirely. I had no idea how to make things easier, or even if I'd done something to make them difficult in the first place. What I did get was that it was paramount that we protect my mom from anything that might upset her, even if I wasn't sure what those things were. So I learned another system: When in doubt, keep it out—out of earshot, out of the house—even if this meant, really, just keeping it in.

My mother's depression, or episode, or whatever it was—I never got a concrete term, which made it all the more hard to define—had been going on for about three months when my dad convinced her to go see a therapist. At first she went reluctantly, quitting after a couple of sessions, but then she started up again, and this time she stuck with it, continuing for the next year. Still, there wasn't some sudden change—one particular day that I came into the kitchen at ten thirty and there she was, bright and cheerful, like she'd been waiting for me to appear. Instead, it was a slow process, little increments, like moving a half a millimeter a day so that you only really notice progress from a distance. First she stopped sleeping all day, then she began to get up midmorning, then finally she started to cook breakfast every once in a while. Her silences, so noticeable at the dinner table and everywhere else, slowly became less extended, a little conversation here, a comment there.

In the end it was the modeling, though, that convinced me we were over the worst of it. Since my mom had been the one who got us to jobs and dealt with Lindy as far as scheduling and auditions, we'd all been working a lot less while she was sick. My dad had taken Whitney to a couple of jobs, and I'd had one shoot that was booked way in advance, but things had definitely slowed down—enough so that when Lindy called one day during dinner about a go-see, even she was assuming we'd take a pass.

"That's probably best," my dad said, glancing back at all of us at the table before taking the phone farther into the kitchen. "I just don't think the time's right."

Kirsten, who was chewing on a piece of bread, said, "Right for what?"

"A job," Whitney told her, her voice flat. "Why else would Lindy call during dinner?"

My dad was rummaging in the drawer by the phone now, finally digging out a pencil. "Well, okay," he said, grabbing a nearby notepad. "I'll just take down the info, but most likely… right. What was that address, again?"

My sisters were both watching him as he scribbled it down, probably wondering what the job was for, and for whom. But I was looking at my mom, who had her eyes on my dad as well, even as she drew her napkin out of her lap, dabbing the corners of her mouth. When he came back in, settling into his chair and picking up his fork, I waited for my sisters to ask for details. But instead, my mom spoke first.

"So what was that about?"

My dad looked at her. "Oh," he said, "just an audition tomorrow. Lindy thought we might be interested."

"We?" Kirsten said.

"You," my dad told her, scooping some beans onto his fork. "I told her it probably isn't a good time. It's in the morning, and I've got to be at the office…"

He trailed off, not bothering to finish—not that he had to. My dad was an architect and busy enough with his own work, plus taking care of my mom and keeping up the house, without having to deal with running us all over town. Kirsten knew this, even though it was obvious she was disappointed. But then, in the quiet as we all went back to eating, I heard my mom take in a breath.
