finding out i am adopted

I was 36 and preparing for the birth of my son. I was living overseas and the powers that be required a copy of my birth certificate to register my son's imminent birth. i only had an abbreviated version of my birth certificate, with my date and place of birth, and the names and dates of birth of my adoptive parents. I was told by the swiss authorities that i had to provide a full birth certificate, so i called my parents to ask if they had a copy. They went all round the houses, saying they didn't have a copy, and advised me to contact register house in glasgow or edinburgh. ten minutes after that call ended, my Dad called me back, and very nervously said, "we do have a copy of your adoption certificate, maybe that's what you need?" and calmy, without batting an eyelid, i replied "of course, silly me, that would be just the thing they are looking for" then i put the phone down, in shock, and called my brother, to find he is also adopted, therefore not actually my blood brother, and that he had known he is adopted for over ten years, but he had said nothing to me cos he thought i was actually the biological child of our parents... so then i cried for three days in shock, and hit an identity crisis that was actually very positive in its outcomes, five years later but hell, quite a shock at the time! There is a lot more i could write, complex stuff, but one thing, very clear, my adoptive parents are just two people who did their best, and who were scared, and possibly even badly advised by the beliefs of the 1960s.. it is too complex to analyse, the emotions, fear, confusion involved... the pain is very real. I can't get angry, even the adoption "experts" in the late 1960s were only following protocol based on their best understanding of the world at that time, and they were pushing this adoption craze all over the anglophone world but not giving adoptive parents the knowledge they needed, because the knowledge was not there yet. I don't know if adoption in the 2000s is any less traumatic than i the late 1960s, one guesses a newly born baby feels the same trauma at separation from its biological mother, but perhaps adoptive parents are given better information and better support now than they were 42 years ago. we need open minds and open hearts.
