Hello SongbirdDaisy --
It's lovely that you can choose such a cheerful name for yourself despite what has happened.
I was betrayed after 15 years with my beloved, and I know what you mean -- that feeling that the world has turned upside down, that the very earth has been cut away from under you. I am 4 years out from that and still recovering. It doesn't take everyone that long, but it happened to me in my senior years.
I hope you are getting support IRL as well as here.
Hugs and hugs.
