Teen Mom 2's Kailyn Lowry popped out her second baby back in November (oh hay, Lincoln!), and girlfriend has been on a mission to get back in shape ever since. Kailyn gained a whopping 50 pounds while pregnant with Linc, and despite the fact that she shed a vast majority of it, Kail just isn't happy about the way she looks.

Kailyn currently has her hands full taking care of two kids while her husband, Javi Marroquin, is away in Texas for a month, and unfortunately she hasn't had time to work out. "Cannot wait to get back in the gym," Kailyn tweeted on March 31. "Wish my weight didn't fluctuate so bad."

Between changing diapers and getting dinner ready, who even has time for fitness, right guys? But it sounds like Kailyn's pretty bummed about her weight — not to mention her self-esteem. "Once I get to a routine I know I'll feel better but right now my self esteem is nonexistent," she added.

Unfortunately, Kailyn has a history of anxiety around her weight, and even battled an eating disorder.  "When I was in middle school, I had a really hard time being called the 'chunky girl,'" Kailyn told Wetpaint Entertainment during an exclusive interview back in 2012. "I would go on bouts where I wouldn't eat or try to make myself throw up. At this point, I am so comfortable with where I am right now."

Kailyn's definitely come a long way since middle school, and we're happy to report that she wants to shed pounds in a healthy and natural way — through diet and exercise! And by the way, girlfriend looks amazing in recent photos from her birthday. Clearly she doesn't have that much more weight to lose until she hits her goal!
