I feel i want to answer here, but i am not quite sure how to word it. As others have said, it is wholly possible that your mother is your biological mother - you only have to look through the newspapers evey now and again to hear of someone not knowing she was pregnant suddenly having a baby.

To actually tackle your question though. Having been adopted, not once but twice, and having one loving parent (1, not 2) - i find it hard to think less of my biological parents. It has taken me a while to get to this point, but i have come to the conclusion now that it doesn't really matter very much, and even if it did i can't change it. I can't offer a magic solution, but i can say that it wouldn't be the end of the world.

Best wishes, Isobel
