Adjusting to Change When Everything Feels New

To cope with change, your nervous system needs two things: something steady to hold onto, and a way to work through the specific worry-images spinning in your head. Keep one or two routines you fully control, then use short rounds of bilateral stimulation (BLS), the left-right technique behind EMDR, to take the edge off the loop that keeps replaying.

Maybe you started a new job, moved to a new city, or your relationship, family, or body just changed shape. Nothing is technically wrong. You wanted this, or at least chose it. And still you feel unmoored, like you’re borrowing a life you haven’t grown into yet, checking your phone for no reason, replaying the same what-if scene on a loop.

Why does change feel so unsettling, even good change?

Your brain treats not-knowing as a bigger threat than knowing something bad. A 2016 study in Nature Communications tracked stress hormones and skin conductance while people faced varying odds of a mild shock, and found the most stressful condition wasn’t the high-odds one. It was the 50/50 one, the point of maximum uncertainty. Change, even change you wanted, puts you squarely in that zone: new job, unknown boss, unproven routine.

That’s also why a welcome change can feel as heavy as a hard one. A 2023 PLOS ONE study updating the classic life-events stress scale scores readjustment “irrespective of desirability,” and finds that events like marriage or a change of residence carry a real, measurable readjustment load, not far off many losses on the same scale. Your nervous system is responding to how much of your routine, identity, or sense of normal has to reorganize, not to whether the news is good. If a wanted change still knocked you sideways, nothing has gone wrong with you.

People also vary in how they meet this. A 2010 review in Clinical Psychology Review describes psychological flexibility, the capacity to adapt your thinking and behavior as circumstances shift, as one of the strongest known links to psychological health. It isn’t a fixed trait. It’s closer to a muscle: the more often you practice meeting an unfamiliar moment without forcing it into an old shape, the steadier that moment starts to feel.

A bilateral stimulation practice for the loop in your head

Big-picture uncertainty is hard to work with directly. What you can work with is the one specific image your mind keeps returning to: the first awkward meeting, the empty apartment, the conversation you’re dreading. Here’s a short practice for that.

• Rate it. On a 0–10 scale, how intense is the worry right now? Note the number.
• Pick the exact scene. Not “the whole transition,” but the single frame on replay, like walking into the new office or the moving truck pulling away.
• Add bilateral stimulation. Move your eyes smoothly left and right for 20 to 30 seconds, alternate tapping your knees or shoulders, or use alternating left-right audio tones, while holding the image lightly in mind.
• Pause and notice. Stop. Breathe. Notice whatever shifted, without forcing anything.
• Repeat 3 to 5 short rounds, checking in between each one.
• Re-rate. Many people notice the number ease and the image feel more like a memory than a threat. If it climbs instead, stop and use grounding: name five things you can see, feel your feet on the floor, slow your exhale. Staying inside your window of tolerance, the zone where a feeling is present but you can still think clearly, is what makes this useful.

The idea isn’t new. EMDR’s own theory, the Adaptive Information Processing model, holds that vivid, unsettled moments can stay stored in a raw way that a related cue keeps reactivating, according to EMDRIA, the professional body for EMDR. A 2013 meta-analysis in the Journal of Behavior Therapy and Experimental Psychiatry found that adding eye movements while holding a distressing image in mind reduced how vivid and emotionally charged it felt, which is the mechanism this practice is built on.

Counting rounds while your mind is already looping is one more task most people don’t want. EmEase, a self-guided EMDR app, runs the same left-right technique for you with a moving on-screen target or alternating tones, at a pace you set, in the web app. The beginner’s guide to self-guided bilateral stimulation walks through pacing if this is new to you.

Give the rest of your day one steady thing

Uncertainty is easier to carry when at least one piece of your day is fully predictable. You don’t need to overhaul your routine mid-transition, that’s often not realistic. Pick one small anchor you fully control, a set wake time, the same walk, one meal you don’t have to think about, and hold it steady while everything else resettles. It won’t erase the newness, but it gives your nervous system one place to stop bracing.

When adjusting to change needs more than this

This practice fits everyday disorientation, the kind that eases as the new normal becomes familiar. If the change involved a real loss, someone gone, a relationship ended, a role you miss, our guide on grief and life transitions goes deeper on that side of it. Consider reaching out to a licensed professional if the unsettled feeling hasn’t started to ease after several weeks, if it’s tangled with grief that disrupts most days, or if distress during this practice rises above a 7 out of 10 and won’t settle. Self-guided bilateral stimulation has honest limits, laid out in can you do EMDR on yourself?, and reaching for more support is a reasonable move, not a failure to adjust.

You don’t have to feel settled to be doing this right. Most people who look steady from the outside are still quietly getting used to the new shape of things, one ordinary day at a time.
