I'm searching for my birth parents my real parents the one's that brought me into this world

Hard to tell what your reasoning for doing such is, particularly not knowing what your experience growing up with your adopted parents was. It obviously can be an explosive emotional minefield for everyone involved. I know people who have successfully done it. First, whatever your real reasons may be for doing so, the undeniable and safest justification is wanting to know your genetic profile to add to your medical history. Treatment is being guided more and more frequently by your genetic history. That takes it out of the emotional minefield. Second, don't be judgmental in how you frame the discussions, the questions. Your adoptive parents may not have done as well as you would have liked, but they did step up when your birth parents didn't feel they could raise you, and they did raise you. And until you track down your birth parents and have a discussion with them, you don't know what the circumstances were that led them to feel you would be better off raised by someone else. And even then, they may not be willing to disclose their reasons. Focus on better understanding what was driving each sides choices & decisions at the time; focus on getting to know your birth parents without making comparisons or criticizing either if you truly just want to know more about how you got to where you are.
