Looking for an angel

I have been searching on and off for my birth mother for many years now. I am hoping that it is not too late for me... she was 20 when I was born, and I am now 36. I was born on February 13, 1978 at Blodgett Hospital in Grand Rapids, MI. I was adopted in (I believe) April of that year by D.A. Blodgett. I have contacted them and received my non-id information, but it has not been very helpful. The only name mentioned in the letter they sent was the name my birth mother gave me when I was born, which is Margaret. She was in college at the time. Please send me a message here or at asaradragon@gmail.com if you think you can help. I don't want much, just to thank her and possibly get some closure. Thank you!
