The Teen Mom-turned-porn star and her mother -- whose stormy relationship was closely chronicled on the hit MTV reality show -- had a falling-out after Farrah decided to get in the celebrity sex tape business via her taped romp with porn actor James Deen.
But Danielson eventually found out the rumors were true, and Farrah moved out of her mother's home two weeks ago, telling a website she decided to leave after a counselor told her the situation was probably too toxic to remain in.
On Friday, however, things looked to be on the upswing with the mother-daughter combo.
The letter, dated 4-25-2013, reads:
Farrah & Sophia,
I miss you both so much! Love you and pray God will bless and keep you safe. Want our family to heal and grow. I will NEVER leave you or foresake you. You are a priority in my life.
XOXO Mom & Grandma
As we previously reported, Farrah has reportedly closed a six-figure deal with porn giant Vivid for distribution rights to her debut foray on film, titled Farrah Superstar: Backdoor Teen Mom.
