That's an awesome feeling! Good for you. Day by day, your confidence will rise.
For me, the point when I knew I passed was the day I changed from caring what people thought, to not caring what people thought. Early on, I never believed the person in the mirror was me. I couldn't take compliments, and I put myself down. Then, some time later, something clicked, and all of a sudden I believed who i was.
I still have a chcukle when people compliment me.
My best moments for passing were two I recall:
Being a grocery lineup, little girl behind me with her dad...she looks at me and says "mama?". Her father said, no, mommy is at home. Lol.
Second one is when women ask if I have children and I say one daughter but she doesn't live with me. Two times someone said, "oh, she's with her father".
