While most women with PMS find their symptoms uncomfortable, a small percentage have symptoms severe enough to stop them living their normal lives.
This is the result of a more intense type of PMS known as premenstrual dysphoric disorder (PMDD).
The symptoms of PMDD are similar to those of PMS, but are more exaggerated and often have more psychological symptoms than physical ones.
As depression is a common symptom of PMDD, it's possible that a woman with PMDD may have thoughts about suicide.
PMDD can be particularly difficult to deal with as it can have a negative effect on your daily life and relationships.
