What to Expect Emotionally During the First Week of Rehab

Feb 15

Walking into rehab can feel like stepping into a completely different life. Even if you’re sure it’s the right move, your emotions can be all over the place in the first week. That’s normal.

You’re leaving behind coping habits, routines, and people (even the unhealthy ones), and your mind and body are trying to figure out what “safe” looks like without the old patterns.

Summary: In the first week of rehab, it’s common to swing between relief, fear, anger, shame, hope, and exhaustion, sometimes all in the same day. You’ll likely feel raw as your brain adjusts, your nervous system settles, and you start opening up. With the right support, structure, and a calm environment, that emotional turbulence usually begins to steady, and you’ll start to feel moments of clarity and confidence that recovery is possible.

The first week can feel intense (and that doesn’t mean you’re failing)

A lot of people arrive expecting to feel instantly better because they’ve finally asked for help. Sometimes there is relief, but it often sits right next to panic, grief, or numbness.

Here’s why it can feel so big:

Your brain is adjusting. Without substances or compulsive behaviours, your mood can bounce around while your system recalibrates.
You’re finally slowing down. When life gets quiet, feelings you’ve been pushing away can surface.
You’re in a new place with new rules. Even a beautiful setting can feel unfamiliar at first, and unfamiliar can trigger anxiety.

If your emotions spike, it’s not proof you can’t do rehab. It’s often proof that rehab is doing what it’s meant to do: giving you space to feel, safely.

Day 1 to 2: relief meets fear (and sometimes regret)

The first 48 hours are often a mix of “thank goodness I’m here” and “what have I done?”

You might notice:

Relief that you don’t have to keep holding everything together
Fear about judgement, treatment, or what life looks like after rehab
Homesickness even if home has been chaotic
Regret about relationships, money, work, parenting, or lost time
Shame that whispers you “should’ve handled it” on your own

A common experience is wanting to leave early. That urge can be strongest right at the start, when your brain is searching for the fastest way back to what it knows. In a supportive program, staff expect this and help you ride it out rather than act on it.

Day 3 to 4: the emotional “crash” can hit

Once the adrenaline of arriving fades, a slump can appear. People often describe it as flat, foggy, or tender.

You might feel:

Exhaustion (deep, bone-tired exhaustion)
Irritability or anger that seems to come out of nowhere
Tearfulness or sudden sadness
Anxiety about the future
Emotional numbness, like you can’t feel much at all

This is also when cravings can show up in surprising ways. Not always as “I want to use”, but as restlessness, bargaining, or daydreaming about the old escape routes.

If you’re in a retreat-style setting, the environment can really matter here. Being surrounded by nature, away from city noise and constant triggers, can help your nervous system settle and make the tough days feel more manageable. Southern Highlands Addiction Retreat, for example, is set on 100 acres in Canyonleigh (NSW) and is designed to feel calm, private, and non-clinical, which many people find helps them stay grounded in those early emotional waves.

Day 5 to 7: small moments of clarity start showing up

By the end of the first week, many people begin to notice short “windows” where they can breathe a little easier.

That can look like:

Waking up and feeling slightly more steady
Feeling safe enough to talk honestly in a session
Realising you laughed at something, and it didn’t feel forced
Feeling proud you’ve made it a week
Starting to believe, even quietly, that change might stick

This doesn’t mean it’s suddenly easy. It just means your system is starting to adjust and you’re beginning to build trust in the process.

The feelings people don’t expect (but are very common)

Grief

Grief isn’t only about losing a person. In rehab, grief can be about losing:

the identity you built around being “fine”
friendships that revolved around drinking or using
time you can’t get back
the fantasy that one day it would “sort itself out”

Anger

Anger can be a protective emotion. You might feel angry at:

yourself
family
the system
the unfairness of what you’ve lived through
the fact you have to do this work at all

Anger doesn’t make you a bad person. It’s often a sign you’re finally letting yourself feel the truth.

Shame (and the urge to hide)

Shame loves secrecy. In rehab, the urge to “keep it vague” can be strong. But a good program is built to gently challenge shame, not amplify it.

If you’re in a private retreat with your own space, it can be easier to settle and open up at your pace. Southern Highlands Addiction Retreat offers private ensuited rooms, which can give people that extra sense of dignity and breathing room in the early days.

What helps emotionally in the first week (practical, real-life stuff)

You don’t need to “perform” recovery. The goal of week one is simply to arrive, stabilise, and start engaging.

A few things that genuinely help:

Stick to the daily structure, even if you don’t feel like it
Routine reduces decision fatigue and helps your brain settle.
Tell staff what’s going on in your head
Especially if you feel like leaving, spiralling, or shutting down.
Keep expectations small
“Get through today” is a perfectly good goal.
Let your body recover too
Sleep, hydration, and regular meals matter more than you think.
Use your environment
A quiet walk, fresh air, and space away from constant noise can take the edge off big emotions.

If you’re heading to rehab soon, here’s what to remind yourself

When emotions spike in the first week, it’s easy to think, “This isn’t working.” A more accurate thought is usually: “This is the adjustment period.”

Try these reminders:

Feeling worse before you feel better can be part of healing.
You’re not behind. You’re in week one.
You don’t have to be brave every minute. You just have to stay.
Support is the point. Let people help you.

FAQs

Is it normal to cry a lot in rehab?

Yes. Many people cry more than expected, especially in the first week. When you remove the usual numbing or distractions, emotions can surface quickly.

What if I feel worse after a few days?

That can be normal too. The first week is a transition period. Feeling low, irritable, anxious, or flat doesn’t mean rehab isn’t working. It often means your system is recalibrating.

What if I don’t feel anything at all?

Emotional numbness is common, especially if you’ve been in survival mode for a long time. It can take time for feelings to return in a safe way.

How long does it take to feel settled?

There’s no perfect timeline, but many people start to feel more stable after the first week as routine kicks in and the environment becomes familiar.

Does a private rehab retreat make the first week easier?

For some people, yes. Having a private room and a calmer, nature-based setting can reduce stress and make it easier to engage with treatment, especially early on.
