I'm adopted and met my natural mother many years ago. It ended sadly as she didn't want the contact as I'd been "kept secret" from everyone and her subsequent kids after me. She had married my birth father a few years after he divorced his wife. My mother had been having an affair with a married man, I was the product.
It was good though, to have made contact, find out about my background and heritage as had always been an itch I needed to scratch.
I totally understand your desires to find out more about yourself. Good luck. Its scarey, and amazing at the same time. xoxox
