Leah Messer is happy and she wants the world to know.

Following a number of harsh rumors in recent years, including reports of cheating, drug use and bad parenting, the Teen Mom 2 star claims to be in a great place.

"No one will ever have the ability to ever strip my happiness and being from me, not even myself! I keep pushing forward, and shining bright through it all!" Messer wrote in the caption of an Instagram selfie on Wednesday. "Key to success = Embracing your trials and TRIUMPHS!! Gods gots a better plan for me than I had for myself! #LYS My growth over time has not just shocked everyone else, but it spooked me at first! It's the best feeling ever! #YOUCAN @liveyourstandard ! What are you waiting for ??"

Just last week, Messer shared another selfie, and in the caption, she again spoke of her happiness.

"There is no greater blessing in life to be able to stand in your very own happiness with who you are and who you are becoming!" she wrote. "The amount of joy peace, and TRUE love that I now can feel is empowering within itself. Don't settle for less than what you deserve. Be YOU, Be a DIFFERENCE! Lets stand TOGETHER for a CHANGE, and teach each other our worthiness and HOW TO: Live Your Very OWN standards! #SetYOURbarHIGH && #NEVERGIVEUP !! Thanks to all who supported me and didn't give up on me! #ILY #Look@MeNow #LetsShineTogether @liveyourstandard @msrielly."
