Teen Mom's Amber Portwood learned a lot during her 17-month incarceration, but she still battles her demons on a daily basis. This girl was locked in the slammer thanks to opting out of her drug court program, but Amber's problems ultimately stem from her anger issues.

After all, if she hadn't choked her baby daddy, Gary Shirley, on Teen Mom, the CPS would never have become involved in her life, and things may have turned out very different.

Amber has a history of being volatile, and fans of Teen Mom have seen her fly off the hand on several occasions — especially during interactions with Gary. Amber has fought to overcome her anger issues, but it's definitely an uphill battle.

This reality star took to Twitter and implied that she still deals with bouts of anger on the regular — but the good news? The lessons she learned in Anger Management are helping her stay cool, calm, and collected. "Anger management is really kicking in right now…" Amber tweeted on May 6 along with a meme that says, "Here's an x-ray of the amounts of f—k I give [zero]."

Uh oh. It's unclear what provoked Amber's outburst of anger (maybe Gary baked her a less-than-stellar batch of cookies), but it's good to know that girlfriend is dealing with her issues head on instead of letting her anger get the best of her.

Are you impressed by how much Amber has grown and matured since ye olden days? Take to the comments and let us know what you think!
