never legally adopted - need medical history NOW!!!

I never was legally adopted. I need my family medical history yesterday!! I have conditions that may be hereditary but I don't know. The tratment will be different if it is hereditary than if it is not hereditary. I have already had surgury once and I can tell it is comming back. Because I don't know my family medical history my doctor referes to it as a "genitic predisposition". If it is not hereditary I will not have to have an aditioal proceedure that will cause me to have infections the rest of my life. Do to it being a "genitic predisposition" I will have this procedure the third time the condition comes back. I've been told that I can't get any informaton because of my bmoms right to privicey. So this is a right to privicy verses right to know issue...due to the fact that I was never even given up for adoption I feel the scale should tip a little toward my side. Maybe a need to know basis.I would like to meet my bmom and my older (and any other) siblings. But have not found her yet. I have both mine and her birth certificates. But nothing else that I know to be fact. I was told that she was going to drown me in the river if my "amom" didn't take me. And that she personaly gave my to my "amom". I was told many more bad things things about her. I have Post Traumatic Stress Disorder from childhood abuse.
