Those of you who came out to your parents, how did they react?

I came out (asexual lesbian) to my mother earlier this week. While nothing catastrophic happened and she acknowledged it, she has also been very cold with me since, either giving me simple one-letter answers or ignoring my messages all together, even casual ones like "how are you," which is really uncharacteristic of her. It was kinda shocking to me and still makes me sad, since I feel we always had a pretty good relationship and she was never really one to be super hateful, and has in the past even given me the "I'll love you no matter what," yet now it feels that she's turned around and I just don't understand why. Part of me hopes that it's just like an initial shock of sorts and she will come around, since that has happened before, but I still worry a little bit and kinda it breaks my heart that something so irrelevant could strain our relationship.

So I would just like to hear other people's experiences. Were your parents negative? neutral? How fast did they come around? What did you do to help them come around etc. idk just anything, thank you
