TEEN MOM STAR AMBER PORTWOOD IS A PILL POPPER!

Despite reported attempts of trying to mend their damaged relationship, the ex-fiance of "Teen Mom" star Amber Portwood has had enough of her shenanigans.
According to Life & Style, Gary Shirley, the father of Portwood's nearly 2-year-old daughter Leah, has already moved out of the apartment the couple used to share in Anderson, Ind. and is moving on with his life.

"Gary loves Amber, but he wants custody of Leah," Shirley's best friend, Jordan Sanchez, tells the mag. "Leah is with Gary almost all the time."

In addition to her hostile attitude, Portwood has been caught on camera punching Shirley several times, including one incident where she punched him hard hit in the face before kicking him in the back as he walked down a flight of stairs.

The Anderson Police Department is investigating the incident as an assault.

As a result of the stress stemming from the possible domestic battery charge, the 20-year-old single mom has allegedly turned to medication to cope.

Sanchez claims the volatile reality star has a prescription for the addictive anti-anxiety drug Klonopin, which is often used to relieve panic attacks. Severe drowsiness and dizziness are said to be among the medication's side effects.

"I worry that she could be abusing it," Sanchez says. "I've seen her take multiple Klonopin at a time. There are days where she sleeps until 7 o'clock at night."

The powerful medication has apparently made Portwood lose her appetite as well.

According to Sanchez, Portwood has become so depressed in recent days that she has resorted to using her problems as a way to win back her ex.

"Gary has told me that Amber is bipolar. It's gotten pretty bad," Sanchez says. "Gary told me that there have been several instances where Amber would say to him, ‘Come home or I'm gonna kill myself,' and he'd fall right into her trap."

However since Portwood's aggressive behavior has taken a turn for the worse, Shirley has reportedly moved out and is taking primary care of the couple's child.

"Amber's always beating on him, verbally and physically," adds Sanchez. "What normal person would stay in a relationship like that?"
