I would like to think God is telling you not to give up hope yet as you've posted here, maybe He is telling you something. It's good you've had a wonderful life and that is credit to your parents - I hope they are supporting you in your search as they will always be your parents (I tell my bson the same).
My bson searched for me for 5 years which included finding my family - long story why they didn't tell him where I was or tell me he had contact with them. I had been told I wouldn't be allowed to search for him and wouldn't have known how to anyway so it was a miracle that I found him. Last year my husband and I decided to trace our family trees and joined Genes Reunited so I was shocked to find my details had been entered on the site already. I took a chance and emailed him anyway and got a response quite quickly.
If my bson's experience of searching is typical it must be a difficult time for you but please don't give up yet - I have never regretted finding my son.
