My mother was a narcissist - a real one, a personality disorder, not just selfish.
Anyway my sister The Golden Child had a hard time dealing with life. Not everybody treated her like she walked on water, like mom did. She was married several times, lots of migraines, etc.
My other sister and I had a lot easier time in adulthood even though our childhood was hell.
I figured my mom had a mental problem so that’s how I was able to forgive her. My sister and I coped by joking and laughing a lot, and did so all our lives. I miss her, when something happens I wish she was still here to laugh with.
Was the Golden Child the oldest?
Glad you and your other sister (younger) had each other had each other.
