• I was diagnosed with ADHD at 38. I spent most of my life masking things I didn't know were ADHD.
• Instead of pretending I'm fine, I tell my sons when my brain is full and my battery is running low.
• I'm teaching them that everybody has different limits and it's important to know and respect them.

There are nights when I look at my two boys, 13 and 10, and announce, "My battery is at 1%."

They know what this means.

I get much quieter. The pile of clothes I told myself I was going to fold gets moved to the floor and becomes tomorrow's problem. Video game sounds that normally wouldn't bother me suddenly send my whole system into overdrive. If both kids are talking to me at once, I sometimes have to say, "I can't process what either one of you is saying right now."

Eventually, I can hit what feels like an actual wall. I go into a burnout shutdown where decision-making becomes almost impossible. My brain feels frozen. I know there are things I should be doing, but I can't organize them into a next step. If I'm overstimulated enough, I can barely formulate a cohesive thought.

Sometimes the only thing that helps is going into my room, closing the door, and sitting in complete silence.

I don't hide this from my kids. I let them see it on purpose.

I spent most of my life not knowing my brain worked differently

I was diagnosed with ADHD at 38. Until then, I genuinely didn't know other people's brains worked the way mine did. The best way I can describe my brain is that there are three musicals happening on three different stages at the same time. There are songs, conversations, ideas, and a constant stream of thoughts all competing for my attention.

From the outside, I looked highly functional. I was an A+ student. I worked hard. I got things done. I became an entrepreneur.

Internally, I was exhausted to the point that it sometimes felt like an existential level.

I remember hitting this same wall when I was around the same age as my sons. My parents didn't understand what was happening, and why would they? ADHD wasn't something anyone was considering for me. I wasn't physically hyperactive. All of the pinging was happening inside my head. So I learned to push through it and, eventually, to look calm while doing it.

In our family, we talk about our batteries

Our family therapist gave us an analogy that has become part of our language: Everybody is like a cell phone. Our batteries drain differently, and they recharge differently.

My older son is an introvert like me. We can love being around people and still need significant quiet afterward. For me, recharging means real quiet — a chunk of time when nobody is talking to me, asking me a question, or needing me to make a decision.

My younger son, who also has ADHD, is almost the opposite. I always say he's fueled by people. Talking to friends and being around other people can actually charge him. I love that distinction because even people whose brains are wired similarly don't necessarily need the same things.

There isn't one correct way to recharge.

I want my kids to know before they're 38

Being a single parent means I can't disappear into silence every time my battery gets low. Sometimes the video game is still playing. Somebody still needs something. Life keeps happening.

I've stopped believing that being a good mother means hiding the fact that I have limits. I'm not asking my children to take care of me. I'm letting them know me.

I want them to understand that people who love each other get to be human in front of one another. You can say, "I need quiet." You can say, "I need people." You can say, "My brain is too full right now." Limits aren't character flaws, and rest isn't something you earn only after you've completely depleted yourself.

For most of my life, I thought strength meant pushing through until nobody could tell I was struggling. I'm trying to teach my kids something different: learn what drains your battery. Learn what charges it. Tell the people you love what you need. And don't wait until you're at 1% to plug yourself back in.

• Makeup and beauty routines have never been very important to me.
• My daughter is obsessed with self-care and knows a lot more about products than I do.
• I'm always happy to indulge her interests in this area; it gives us a nice way to connect.

"Can we go to Sephora?" my daughter asks, with her rather flawless teen reflection in the mirror standing on a blush-stained rug. Excited that she asked me into her room, I think, "Sephora again?"

With no room for more makeup around her cluttered sink, I question the need for any more beauty products. At the same time, my daughter is asking to spend time with me. "Pick up the towel off the floor and pull up your Oliva {Rodrigo} playlist," I say, smiling as I walk out the door. "We are leaving in five."

I learned to embrace the suck

As the true definition of a tomboy, now in my early 50s, my makeup knowledge ends with applying lipstick and mascara — without smudging.

Walking through the aisles of makeup and skincare products, I read the labels, dumbfounded. What even is skin milk? Would I apply that before or after serum?

Just as I tell my daughter the coined elementary school phrase, "The power of yet, you can't do it yet," when she struggles with things, I have learned to accept that I don't feel confident applying makeup or following my skincare routine yet. Not long ago, she flipped those words back on me, the ones I so often tell her, as I struggled to apply eyeshadow while we got ready for a concert together: "Accept that struggle is part of the learning process." If embracing the suck means more quality time with my daughter, please sign me up over and over again.

I let her lead

Life lessons, especially in the tween and teen years, come fast and often. Relating to teen interests and experiences is also harder than it used to be in this modern, technology-driven world. My daughter's obsession with self-care has given her a chance to teach me a thing or two about what matters to her. She's created a space for us to share experiences on a platform she understands and values.

On a recent trip, I fumbled through the 20 or so shades of skin tint with SPF. Putting up my I-give-up hands, I watched my daughter take my wrist and rub a shade of tint on the back of my hand. "You need something a bit darker," she said, grabbing a darker shade and taking the lead with the confidence of a well-trained beauty store employee.

Who would have thought the back of your wrist was a good place to match your face foundation? I sure didn't. I'm not raising my hand in the back to say I know the difference between essence and face oil, but ask my daughter, and she'll exude self-assurance and rattle off the answer with a smile.

I have savored our time together

Between work and school commitments, friends, and extracurriculars, it's hard to find time to just hang with my teen. Besides a before-school Starbucks run, a trip to the beauty store is one date my daughter never says no to.

I know the last time we do our Sunday self-care routine of gossip, masks, and eye patches will come. Some day she might even want to shop for makeup just with her friends. For now, I'll keep singing Olivia at the top of my lungs with her in the car on the way to and from the store. Even if I always feel like a fish out of water in a beauty store's sensory overload, I will embrace it all for some one-on-one time with my daughter. Plus, my skin has never looked better.
