The short explanation
Yes, there are things that help. Mood changes, irritability and tearfulness in the week or so before a period are part of premenstrual syndrome, or PMS. They are linked to the way the brain responds to normal hormone changes in the cycle, not to a weakness in your character. Many women feel exactly as you describe, including the guilt afterwards. Things that help some women include regular physical activity, steady sleep, eating regular meals, cutting down on caffeine and alcohol, and planning lighter days in the premenstrual week where possible. Talking therapies, especially cognitive behavioural therapy, have good evidence. If lifestyle changes are not enough, a clinician may suggest treatment, including hormonal or other options.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Tracking your mood for two or three cycles alongside your period dates is very useful. It shows whether the symptoms really come and go with the cycle, which helps a doctor tell PMS from ongoing low mood or anxiety.
- If the symptoms are severe enough to damage relationships or work, the doctor may consider premenstrual dysphoric disorder, a more intense form that also responds to treatment.
- It can help to explain the pattern to people close to you, so they understand it is not about them.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether your symptoms are PMS or something else, such as depression that gets worse before periods. A doctor needs to hear your history and see your tracking.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Do my symptoms fit PMS, or should we consider PMDD or depression?
- What can I try first, and what are the options if that does not help?
- Would talking therapy be useful, and where can I get it?
- How should I track my symptoms for our next visit?
