How excited are you about Teen Mom 2's upcoming season (aka Season 5B)? We cannot wait to catch up with Kailyn Lowry, Jenelle Evans, Chelsea Houska, and Leah Messer when they hit up the small screen on July 16, and from the looks of this new sneak peek, we're in for some serious ugly-crying.

All of the Teen Mom 2 stars lead pretty emotional lives, but Leah and her baby daddy, Corey Simms, have it particularly rough since their daughter, Ali, has a developmental disorder called Titin Muscular Dystrophy. Ali's spent much of her life in and out of specialist doctors appointments, but she's never been aware of her condition...until now.

In this sneak peek clip from MTV, Corey drops the kiddos off with Leah in some desolate parking lot (seriously, they need to find somewhere better to meet), and explains that Ali is well aware of her diagnosis.


"The other day when we got her home she said, 'Daddy, I'm not strong because I have Muscle Dystrophy. And I can't do a lot of things.' I don't know what 4 year old knows that.'" Corey tells Leah. "I don't understand how she would all of a sudden tell me that. I about lost it."

This is incredibly sad, but Leah reminded Corey how important it is that their little girl be taught to try, try again. "Right now she's young and she's gonna play pity party," Leah explained to her ex. "We are her parents to lift her up. You fall you get back up. You keep doing it." UGH, our emotions.

This season of Teen Mom 2 looks like it's going to be 100 percent unmissable, but will you tune in on July 16? Tell us below!
