To raise awareness and educate GPs and health practitioners.
1 in 20 people of menstruating age suffer, but it’s rare to meet a GP who has even heard of the condition. GPs are the gatekeepers to information for patients, but many are left to suffer alone for years being told they have mental health problems.

To gain more referrals to specialist gynaecologists for sufferers.
With better knowledge by GPs about PMDD, more patients can gain access to specialists (PMS Specialists/gynaecologists) and get the tailored help they need. 

To raise awareness within Mental Health Organisations and educate about the warning signs.
Treatment can (and should often) be very different to that often used for non-hormonal depression or psychosis.

To raise awareness among the general public.
The more people that know about PMDD the better: The more people that talk about it, the more likely it is that sufferers will hear about it and make that connection (often referred to as the ‘lightbulb’ moment!)

To raise much needed funds for NAPS (The UK Charity representing those with severe PMS/PMDD)

To give a strong voice to those who are often shamed by the stigma and embarrassment caused by extreme PMS. 
Often brushed off (even by professionals) and trivialised as something that anyone who menstruates has to ‘deal with’ is just not good enough. Every month some sufferers are losing 2 weeks (or more!) dealing with suicidal fixation, extreme anxiety, extreme fatigue and anger (to name just a few of the common symptoms). With symptoms often heightening after childbirth, partners, children and the wider family will be affected too.
