Why does the dread start on Sunday afternoon?

Because anticipation scales with proximity, not with content. Nothing changes at four on Sunday except how close Monday is, and a predictable stressor produces reliably timed arousal.

Is it a sign I should quit?

It is a sign worth reading rather than obeying. Write down precisely what you are dreading for three weeks. If it is consistently the same specific thing, that is actionable; if it is generalised, look at load and sleep first.

Does a Sunday lie-in help?

It feels restorative and it costs you Sunday night, by shifting your clock later. Keeping wake time roughly constant across the week is one of the most effective changes available here.

Sunday night dread: the anticipatory anxiety with a timetable

Around four on Sunday something shifts. The weekend is technically still happening and you are already in Monday. By nine you are checking email you cannot act on, which converts a bad feeling into a bad night.

Do this now

Close Sunday properly

10 minutes

Write Monday's three things down — actual next actions, not projects. Then close the laptop and put it away.
Do not open email. Whatever is in there cannot be acted on tonight, and reading it costs you the evening.
Ten minutes of slow nasal breathing, in for five, out for five. Sitting, lights low.
Then do one thing that is unambiguously yours — a walk, cooking, a film. Something with a beginning and an end.
Same bedtime as a weekday. The Sunday lie-in is what makes Monday morning worse.

Run it with a timer

Anticipation has its own physiology

Waiting for a stressor produces sustained arousal rather than a spike: raised cortisol, reduced heart-rate variability, poorer sleep. Because Sunday is predictable, the anticipation is reliable, and because nothing has actually happened, there is nothing to resolve — which is why the feeling is so resistant to reassurance.

The weekend sleep shift makes it worse

Later nights and later lie-ins at the weekend shift your body clock westward by an hour or two — social jetlag. Sunday night then asks you to sleep at a time your clock now considers early, which produces exactly the lying-awake that Monday pays for. This is a measurable, common, and largely fixable contributor that has nothing to do with how you feel about your job.

Checking email is the accelerant

Reading work messages on a Sunday evening starts the cognitive engagement without the ability to act, which is the worst combination: full arousal, zero progress. Detachment is the specific ingredient the recovery literature identifies as protective, and an open inbox is the most efficient way to prevent it.

What changes it, over a week

Friday, last 15 minutes
Write next week's three priorities and a clean shutdown note. Most Sunday dread is unfinished Friday.
Saturday and Sunday
Keep your wake time within an hour of weekdays. Social jetlag is half of the Sunday-night problem.
Sunday from 5 p.m.
No email. Ten minutes of slow breathing, then something with a beginning and an end.
If it is every week
Write down what specifically you are dreading. If the answer is the same person or the same meeting, that is information, not anxiety.

When this is not a breathing pattern

See a clinician — promptly, and before assuming any of this applies to you — if any of these describe you:

Dread that is present most days rather than only Sundays
Low mood, hopelessness or loss of interest for more than two weeks
Sunday drinking that has become routine
Dread of a specific person or situation at work involving bullying or harassment — that is a workplace matter and needs raising, not managing
Any thoughts of harming yourself — contact your doctor or a crisis line today
