Evelyn isn't anyone.

We're everyone.

Everyone who’s been ignored, dismissed, or disadvantaged because of biology.

Founding roots

That’s one of the main reasons I started Evelyn. I became aware of PMDD because someone close to me found out they might have it. When searching online for ways in which I could support them, I found very little. Considering how life-changing, and life-threatening, this condition is, I couldn’t believe the lack of research, help, and solutions on offer.

As humans, we’re very good at disassociating from things that aren’t pleasant, especially if we’ve never experienced them first-hand. We never know how inaccessible shops are until we’re pushing a pram or a wheelchair. We never know what it’s like to have an allergy until our child has a severe reaction. I don’t shy away from the fact that, as a man, it wasn’t until I had my daughter, that the reality of PMDD hit home.

I can’t have her growing up in a world where she’s expected to ‘just get on with’ half a life full of pain, anxiety, depression, and worse. The value of empathy is huge, and it's abundantly clear how much work is needed to change the world's perception of female health. It isn’t an afterthought or an option, it’s a necessity.
