Found out I was adopted at age 17

I saw my birth certificate and noticed that it listed that I was born in Florida not Illinois where I thought I was born. My mother and I were sitting in her office. She knew that no one would be coming in that afternoon. She gave me the birth certificate and quietly sat at her desk. Then she told me what she knew. It was August 1980, about a month before my 18th birthday. I remember my jaw dropped and I sat there listening to what she was telling me. It was hard for me to believe. My birth parents were teens. I was born in Florida and given up for adoption at birth. The year I was born was 1962. At that time most children born to parents who were not married were put up for adoption. Abortion was illegal at the time, so most people didn't take this option. Now things that didn't make sense made sense. I don't look anything like anyone in the family. I have dark brown hair and blue eyes. It seemed very odd to me why other family members or at least one family member didn't have the same. Everyone either had blonde hair or blue eyes or dark brown hair and hazel or brown eyes. I remember at age 10 asking my mother why I didn't look like any family members. Later that evening she showed me a picture of her and her brother (my uncle). They were children, my mother was 5, my uncle was 8 years old. Both didn't look anything alike but they both were clones of their parents. My mom had a strong resemblance to my grandmother and my uncle looked like a clone of my grandfather. I didn't see that at the time. My interests are very different than my family. I knew something about me was different but never could put a finger on it till then. This explained a lot of things. I was never supposed to find out about this but because I needed a birth certificate for something, my mother had to produce it. If my mother didn't have to tell me, she never would. This is the old school of thought regarding adoption. I never had any anger towards anyone about the adoption itself. Never was angry with my biological parents or adoptive parents. What I did have anger about was the lies that my adopted parents were told and the lies that my biological mother was told. My mother never wanted to believe that certain people lied to her. The attorney in Illinois who was handling the case for my mom was also lied to several times. He normally didn't handle adoption cases and wasn't familiar with Florida adoption laws. She wanted to believe that they were mistaken or heard something wrong. In contrast, my birth mother was very angry and bitter about the lies. When she contacted me in 1994 and when she visited me in 1998, I found out more and it blew my mind. The parents that raised me had nothing to do with the lies and deceptions, nor did their attorney have anything to do with the deceptions (this was regarding payment for the adoption which was about 3 or 4 times what the average cost of an adoption was in 1962). I don't know the whole story but a couple of individuals got double or triple what they should have gotten for the adoption. At the time this was not illegal, but certainly was unethical and immoral. You couldn't do this today. What surprised me was my mother response when I told her this. She said that it didn't matter to her, because she got me and that's what she wanted, a baby girl. I still think that she didn't want to believe that anyone did anything wrong. As my grandmother said, 'The truth always comes out." And it did. I've since found out that lies and deceptions regarding adoptions were common during the 1950's and 1960's. At least my records weren't altered as some people have discovered, Stuff was left out rather than altered.
