My mood collapses before every period. Is that a real thing?

An AskHer answer: what is known, what depends on you, and what only a clinician can decide.

Nobody asked this one. AskHer’s editorial team wrote the question to open the topic. It is not anyone’s submission, and nobody’s own words are in it.

The short explanation

Yes, and it has a name. Mood, irritability and anxiety that arrive in the one or two weeks before a period and lift within a few days of it starting are premenstrual, and when they are severe enough to damage work or relationships the pattern is called premenstrual dysphoric disorder. It is recognised, and it is treatable. What distinguishes it from depression running underneath is the clearing: a symptom-free stretch after the period. Keeping a simple daily note across two or three cycles is what makes the diagnosis possible, and it is the single most useful thing to take to an appointment.

What depends on your situation

The parts of this that change from woman to woman. Uncertainty is stated, not hidden.

  • Treatment options include approaches to the cycle itself and approaches to the mood, and which is offered depends on what else you want from a method and on your history.
  • The pattern can change over time and often intensifies in the years before menopause, which sometimes surprises women who had managed it for decades.

What this answer cannot determine

The boundary of online education. These need a clinician who can see you.

  • This cannot tell you whether your pattern fits, whether something else is contributing, or which treatment would suit you. A diary over two cycles will tell a clinician more than any description written afterwards.

Questions for your clinician

Take these with you. You can add any of them to an appointment card.

  1. Here is two cycles of notes — does this pattern fit?
  2. What are the treatment options, and what is each one aimed at?
  3. Could anything else be adding to this?
  4. How long before we would know whether something is working?

When to seek help

Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.

  • Seek help today for thoughts of harming yourself at any point in the cycle. A symptom that comes and goes with a cycle is still an emergency when it is that.

Explain more simply My question is different

“Explain more simply” asks you which part was hard to follow, so the author knows what to rewrite. “My question is different” opens a private follow-up with this answer attached.
