Amber Portwood

 Anderson, Ind. police responded to a call that indicated that Amber Portwood was depressed and threatening to end her life. Ultimately, the Teen Mom star was transported to a local medical facility, where she has been receiving treatment. While the reality TV personality has yet to comment on events of that day, Portwood, 21, did open up to PEOPLE last summer about her struggle with bipolar disorder – a condition characterized by dramatic shifts in mood. 
“I take medication,” she said at the time. "I haven't [taken] anything today. Am I acting crazy? This is me though, and I like it."

Portwood, who was shown on the MTV series visiting a therapist shortly after giving birth to her daughter Leah in 2008, said that she was diagnosed with bipolar disorder that year, after a particularly depressing time.

At that time, "I was like, 'Screw this day, but I gotta get up for Leah,'" Portwood said of her mindset. "I just thought I was lazy."

Even so, Portwood wasn’t convinced that her diagnosis was accurate.

"I don’t think I'm bipolar, to be honest with you," she said. "I'm just really outgoing. I think everybody thinks they're bipolar these days. You're a teenager, you have hormones. You're gonna switch up every two seconds!"

According to a source, Amber has been in therapy for two years. MTV did not reply to requests for comment.
