Does Leah Messer have something to prove?

Following a stint in rehab last year for what she claimed was anxiety and depression, the Teen Mom 2 star has been going on and on about how happy and healthy she is today.

In one of her latest social media posts, an Instagram selfie, Messer told fans, "I've never in my life been as happy and healthy as I am now! I definitely believe whole heartedly that the vitamins I take has impacted my health emotionally and physically."

Messer also added the hash tags, "#Happy," "#Healthy" and "#Blessed."

Days later, Messer posted a couple of photos from SnapChat, along with the same hash tags, and a short time before that, she shared yet another series of photos with the same comments.

"So HAPPY just being me!" she wrote with three selfies last week. "#Beautiful #Blessed #Grateful #Happy #Healthy #Strong #Confident I challenge you to post the most natural picture/s of you under this post && on your IG ! Who cares what ANYONE thinks! #BeYou #BeFree #BeLove #BeHAPPY #LIVEYOURSTANDARD."

Messer has also been making sure fans know that she's now feeding her children properly. After being seen on Teen Mom 2 feeding her youngest daughter an icing packet in one scene and a sugar packet in another, she shared a picture of a proper home cooked meal.

Messer and her family are currently in production on the upcoming season of Teen Mom 2.
