Leah Messer is firing back at reports that claim she has become suicidal.

The former Teen Mom 2 star shut down the tabloid reports on Thursday, tweeting "Articles that are sent to me are unbelievable ! I am far from being suicidal because my girls need me happy and healthy! #craziness."

The 23-year-old West Virginia native completed a 30-day rehab stint in June and lost custody of her 5-year-old twin daughters with ex-husband Corey Simms, Ali and Aleeah, in October.

Dr. Drew, who has moderated several Teen Mom reunion shows, said backstage at the Rachael Ray Show that he was "expecting progress" from Messer.

"One of the signs I noticed was that the people around her -- like her ex-husband and his new wife -- were starting to really come down on her," he explained. "When that starts to happen, that's a sign to me that the identified patient is getting better."

"I don't know if this recent issue with the child custody is going to set her back, but I certainly wish her the best," Drew added. "She is working very hard and this has been a terribly painful and stressful time for her."

Simms won custody of the twins on his second attempt, when school records reportedly showed that the girls had often been late to school. The move started rumors that Leah's other ex-husband, Jeremy Calvert, might file for primary custody of his 2-year-old daughter with Leah, Addie.
