It sounds as if you're coping so well under the circumstances. Kudos to you.
I'm lucky enough to have 2 beautiful children, and most of the time I can keep up with them, but on bad days its hard.
After struggling with my periods since they started I am still yet to be diagnosed and taken seriously. Even through I know that I have Endo.
My GP said that none of my symptoms relate to endo. Awful stomach pain, very heavy periods, bad pelvic area, bad back and legs, IBS symptoms, bladder issues, and fatigue. Also the fact that my mum and both grandmothers had it means nothing as according to her It isn't hereditary.
She said that some women just have bad periods and maybe I'm a 'bit hormonal'. She suggested the mirena coil. I've heard mixed reports so doing some research at the mo. I can't understand how the problem can be attempted to be solved if it's not formally diagnosed.
This seems a good network for support
