to panic.. or not?

What defines me as a woman?
(stupid question, i know, so just shut up. NO MENTIONING THE BOOBS!!)
I went to the doctor today, (again).
I've been having insane cramps around my period the last months, and also during sex.
Its gotten worse and worse, to the point that my nice friendly understanding (totaly scary!!) doctor sent me to a specialist.
I might have this http://www.apotek1.no/raadogtjenester/raad/intim_og_underliv/endometriose?gclid=CIHM8Zf4o5cCFQsh3godwCSmDA
Worst case scenario, they have to remove my ovaries.
That means no chance of having babies. Ever.
So what defines me as a woman?
I just want to curl up in my bed and sleep for a week.
I've always known I wanted children at some point, I have their names picked out.
I'm completly lost.
