There’s been some buzz about Leonie Martin, who was St. Therese of Lisieux 's sister.
Her cause is up for canonization, and she had a lot of emotional problems and social development issues growing up.
She became a nun, like her sisters, but it was never easy for her–she worked hard on the virtues.
Some people think she might have been on the spectrum, although I suspect ADHD from some of the descriptions of her childhood behaviors, but in the end, she was a simple, holy woman who put in a sincere effort to serve the Lord.
