Baby Girl Thompson, Born 02/08/1983

I'm trying to find out some information about my birth parents, either one or both would be a miracle for me. I was adopted sometime in the three months after I was born, which was on February 8, 1983. My adoptive parents, the only parents I have ever know, are absolutely wonderful people, married 46 years, and I have never had the courage to ask them about my life before them, because I just feel that it would be painful for them in some way. Recently I was retrieving my birth certificate from their house and I stumbled across some paperwork from their adoption process, on which I was named "Baby Girl Thompson." I'd assume that either my birth mother or birth father had the last name Thompson. That's all I have, other than my own birth date and the fact that I am alive and well and VERY curious about where I come from. Any information would be helpful. Thank you for taking the time to read this, even if you cannot help me to find what I am looking for!
