I'm so happy that your parents reacted the way they did! In the past when I saw some of my friends' results of coming out, I saw mostly their parents flip their lids and go to extremes such as psychiatric treatment with a list of meds to "normalize" them. The whole process was cruel.
I am struggling with whether or not to come out to my mother because of her health, though other than her health, I am not sure how she would react. She was once part of the LGBT community, and I say once because she eventually married again to a man and so that threw me off as to what her true identity / orientation is. I love her no matter what, but have always been too scared to ask her since I thought it would be a form of putting her on the spot, resulting in hurt feelings.
