Pete Davidson has always been candid about his mental health. Having lost his father, a FDNY firefighter, during 9/11, he previously told "The Breakfast Club" he's struggled with suicidal thoughts in the past.

Feeling particularly off in the past year, Davidson checked himself into rehab, hoping to quit his marijuana use. When doctors told him he actually has borderline personality disorder (BPD), he was scared, but he told "WTF With Marc Maron" that he's now coming to terms with the invisible illness.

Davidson admitted he originally thought that he was dealing with feelings of "blind rage" due to his marijuana use.

He revealed he's experienced mental breakdowns where he would "freak out" and then not remember what happened afterward. Other than weed, he said he's never used any drugs so he wasn't sure what was going on.

This, he explained, is why he took a brief hiatus from "SNL" to enter rehab. During his time in rehab, his doctors told him he might have bipolar disorder and encouraged him to take medication. When this medication, which he took while still smoking pot, led him to have another mental breakdown, doctors realized he actually has borderline personality disorder.

Discovering his diagnosis wasn't easy for Davidson, but taking the steps to figure out what was wrong and speaking out about the disorder sets an important example.

"This has been the worst year of my life, getting diagnosed with this and trying to figure out how to learn with this and live with this," he said during the podcast. But while discussing his new medications, he explained, "It is working, slowly but surely."

It's incredibly valuable when a young celebrity like Pete Davidson brings awareness to issues such as BPD. Over 4 million people in the US have been diagnosed with BPD, according to Very Well, yet it's so rarely discussed.

It's not surprising that Davidson is using his platform to raise awareness.

During his previous "Breakfast Club" interview, he spoke in great length about how Kid Cudi's candidness while discussing mental illness saved his life. 

The artists we look up to can have a tremendous influence on us, and when they make a point of sharing personal details with us in order to make us feel less alone, it can change lives. Shattering the stigma around mental health is so crucial, so we hope more celebrities speak out like Davidson.
