The Teen Mom 2 star told fans about her tragic past on the Thursday, October 18, episode of her podcast, "Life Reboot."
"I had this expectation of who I was supposed to be as a mom, as a wife, as a person and I … just never reached them," she said.
Messer revealed she got better and realized "this life is worth living."
The MTV star said what helped her was typing up motivational words and hanging them up on her mirror so she could view them every day.
Messer, 26, noted, "It's like I had to train my mind to know that I am love, I am confident, I am worthy and until I said that repeatedly to myself and like, it just did wonders."
RadarOnline.com exclusively reported in 2015 that following the custody loss of her beloved twins, friends feared Messer was "suicidal" following the devastating blow.
"Leah seems deeply depressed, and everyone is very concerned," a family insider told RadarOnline.com at the time about the mother of three, who lost primary custody of her then-6-year-old daughters Ali and Aleeah to her ex-husband, Corey Simms after a long, nasty court battle. "She can’t imagine life without her girls."
Messer's life has smoothed out as she now spends lots of time with the twins, 8, and daughter Addie, 5, whom she shares with Jeremy Calvert.
But she confided that when Ali was diagnosed with muscular dystrophy, "I cried, oh my gosh, it was unbearable. But in that moment I realized that she is an incredible little girl that's going to do incredible things in this life no matter what she has, no matter what she goes through."
Messer added, "Today I would say that I am kind, I am loving, I am confident, I am courageous, I am strong."
