I am scared to get this

Premenstrual dysphoric disorder (PMDD) is a very severe form of premenstrual syndrome (PMS). It causes a range of emotional and physical symptoms every month during the week or two before your period. It is sometimes referred to as 'severe PMS'.PMDD occurs during the luteal phase of your menstrual cycle. This is the time between when you ovulate and when your period starts. The luteal phase lasts approximately two weeks for most people but can be longer or shorter.
During this time you may experience PMDD symptoms every day, or for a few days within the phase. The NHS website has more information on the stages of the menstrual cycle and when they occur.

Many of us may experience symptoms of PMS. But if you have PMDD, these symptoms are much worse and can have a serious impact on your life. Experiencing PMDD can make it difficult to work, socialise and have healthy relationships. In some cases, it can also lead to suicidal thoughts.
