Why Do I Cry for No Reason?

Usually there is a reason, just not an obvious one: stress, being tired or hormones. How to figure it out, and when it's worth talking to someone.

Common questionA question we hear a lot

Sometimes I just start crying and I don't even know why. Nothing bad happened. Is something wrong with me?

You’re doing homework, or scrolling, or sitting in the car, and suddenly you’re crying. Nothing happened. You can’t explain it, which somehow makes it feel worse.

First: crying isn’t a sign that something is wrong with you. It’s one of the ways your body lets out feelings. And when it seems like there’s “no reason,” there’s usually a reason that’s just hard to see in the moment.

Common hidden reasons

Stress that’s been building up

Tests, friend drama, family stuff, a full schedule. You might handle all of it fine during the day, and then one tiny thing tips you over. It’s not about the tiny thing. It’s everything underneath it.

Being really tired

When you’re short on sleep, everything feels bigger and harder to handle. A lot of “random” crying happens late at night for exactly this reason.

Your period

If you get periods, check where you are in your cycle. According to the Office on Women’s Health, premenstrual syndrome (PMS) shows up about a week or two before your period, and its emotional symptoms include mood swings, irritability, anxiety, sadness and crying spells. Tracking your cycle in an app can show you a pattern.

Feelings you haven’t named yet

Sometimes you’re sad, lonely, worried or overwhelmed about something you haven’t let yourself think about. Crying can be the first sign.

What to do when it happens

  • Let it happen. Fighting tears usually makes them last longer. Find a private spot if you need one.
  • Breathe slowly once it starts to ease.
  • Drink some water and eat something if you haven’t in a while.
  • Ask yourself one question: “What’s been weighing on me lately?” Write down whatever comes up, even if it seems small. These journal prompts can help.
  • Tell someone you trust: “I’ve been crying a lot and I’m not sure why.” You don’t need to have it figured out.

When it’s worth talking to someone

Crying sometimes is normal. But the National Institute of Mental Health says that if you’ve been feeling sad most of the time for a few weeks or longer and you can’t concentrate or enjoy the things you used to, it’s time to talk to a trusted adult about depression. Other signs to pay attention to: feeling empty or worthless, getting irritable or angry easily, or big changes in your sleep or appetite.

Depression is common and very treatable. Telling a parent, school counselor or doctor is the first step. Here’s how to ask your parents for a therapist.
