Neha was nineteen and in her second year of engineering. Her mother brought her to me because she hadn't slept properly in three weeks. When I asked her what was keeping her up, she didn't mention exams or grades. She told me about a conversation with her roommate. Just a small disagreement about something ordinary, who forgot to switch off the geyser. It had happened three days before her first sleepless night.

"I know it's stupid, doctor," she said. "It was nothing. But I keep thinking about what I should have said instead. And then I think about what she must be thinking about me now. And then I think maybe I was wrong. And then I think no, she was wrong. And it just goes round and round."

I told Neha that what she was describing wasn't thinking. It was a loop. There's a difference. Thinking moves you toward some kind of clarity. A loop takes you through the same scenery again and again and drops you back where you started. And the worst part is that it feels productive, like you're working through the problem, when actually you're just wearing a groove in your mind.

The Replay Machine

I've seen this pattern in hundreds of patients. A conversation that didn't go well. A text message that could be read two ways. A look from a colleague in a meeting. The mind grabs onto it and won't let go. It replays the moment, edits it, imagines different responses, predicts what the other person is thinking, and then loops back to the beginning and starts over. All of this usually happens at night, when there's nothing else to distract the mind and the ceiling becomes a screen for your worst interpretations.

In my experience, telling yourself to "just stop thinking about it" is the single most useless piece of advice anyone can give. The harder you push the thought away, the louder it comes back. It's like trying to hold a ball underwater. The more force you apply, the harder it pops up.

What I Suggested to Neha

Over our first few sessions, I gave Neha three things to try. Not as a numbered list of tips, but as experiments. I told her to try each one and tell me honestly what happened.

The first was the worry window. I asked her to pick fifteen minutes in the evening, say 7 p.m., and make that her designated worrying time. Whenever the loop started during the day, at college, in the hostel, before bed, she was to gently say to herself, "I'll think about this at 7." Not push it away. Just postpone it. She thought this was ridiculous. But she tried it. By the second week, she told me something interesting. "Doctor, when 7 p.m. comes, I don't even want to think about it anymore. It seems smaller by then." That's exactly the point. When you give worry a container, it stops spilling over everything else.

The second was the 10-10-10 question. When a thought was spiralling, I asked her to pause and ask herself: will this matter in 10 minutes? In 10 months? In 10 years? The geyser argument with her roommate? It would matter in 10 minutes, maybe. In 10 months, neither of them would remember it. In 10 years, they might not even be in touch. This question doesn't make the feeling disappear, but it helps you see the actual size of the problem instead of the size your anxiety has inflated it to.

The third was the body redirect. Overthinking lives entirely in the head, na? It feeds on stillness, especially late at night when you're lying in bed with nothing to do but think. I told Neha that when the loop started at bedtime, she should sit up, put her feet flat on the floor, and press her palms down on the mattress. Feel the texture of the bedsheet. Notice the temperature of the room. Listen for any sounds, the fan, someone's phone buzzing in the next room, a dog barking outside the hostel. Move her attention from her thoughts to her senses. This is a grounding technique, and it works because your senses can only register what's happening right now. They can't replay last Tuesday.

What Changed Over the Next Few Weeks

Neha came to see me four times in total. By the third session, she was sleeping better. Not perfectly, but better. She told me the worry window had become a habit. She told me she'd used the 10-10-10 question on an argument with her mother about career choices and it had genuinely helped her calm down. She told me the body redirect didn't work every time, but it worked often enough that she trusted it.

What I noticed most was that she'd stopped calling herself "stupid" for overthinking. She'd started to see the pattern for what it was, not a character flaw, but a habit her mind had developed. And habits, once you see them clearly, can be changed.

When It Goes Deeper

I want to be honest about something. These tools are genuinely useful for the everyday overthinking that most of us experience. The replayed conversations, the 2 a.m. spirals, the "what if" loops. But if the overthinking is constant, if it's been going on for months, if it's affecting your ability to work or eat or maintain relationships, then it's worth talking to a professional. A psychologist or counsellor can help you understand what's underneath the loop. These techniques are tools, not treatment. And there's nothing weak about asking for the right kind of help.

Neha is doing well now. She messages me once in a while, usually during exam season when the loops try to come back. She handles them. She has her tools. And that, in the end, is what I wanted for her. Not a mind that never worries, because that's not realistic. But a mind that knows what to do when the worrying starts.
