Bam Margera has always been a little bit off the rails. From his first appearance on Jackass, he's been known for playing pretty gnarly pranks which always fell just on the right side of funny. But, in the wake of the death of his best friend, Ryan Dunn, in 2011, it seems like things have only been heading downhill for the skate star, including various stints in rehab and some very public meltdowns.

In recent months, he's been on a pretty consistent downward spiral, including an episode of screaming at his manager in public, then being begged by his family to return to a behavioral facility for his own safety. But his latest actions (which began after he was kicked off his flight for being drunk and disorderly) really don't look good for Margera, and the internet is feeling pretty worried.

And now Bam's family have spoken out, revealing the reason that they think he's struggling so much.

But then, tragedy struck.

In 2011, Ryan Dunn was driving under the influence of alcohol and crashed his car in Pennsylvania. There were two fatalities - Dunn, and passenger, Zachary Hartwell.

Since losing his best friend, things haven't been going so well for Bam.

He's displayed persistently more and more erratic behavior, including increased reliance on drugs and alcohol, and pretty bizarre and frightening mood swings.

After this March outburst, Margera was committed to a facility.

He was checked in for addiction issues and a suspected personality disorder. Reports state that this was against his will and at the insistence of worried family members.

And since this, Margera has been letting it all out on his Instagram.

In just the past two days, Margera has posted upwards of fifty horrifying posts, which fans have described as being like "watching a documentary about the last days of someone's life." It all started with a screenshot of a text with his ex, Nicole Boyd, with a caption dragging her name through the mud.

And things have only gotten worse from there.

Margera then posted some scrawled handwriting denigrating, not only Boyd (with whom he shares a two-year-old-child), but also his own mother, April. Fellow Jackass star, Chris Pontius, left a heartfelt public comment on the post, saying: "To Everybody asking the Jackass Guys to help Bam, We are trying and have been, but no matter how loudly help screams his name, it’s up him to want to be better and not somebody who publicly degrades their Wife and Mother and takes accountability for it. I wouldn’t write this publicly, but we all get told to go help Bam so much, I might as well answer."

Another Jackass co-star, Brandon Novak, then reached out.

But Bam was having none of it, screenshotting the message and captioning it, "Novak writes me after how long?"

He continued to air his conversation.

Fans aren't finding this drama entertaining or amusing, and are, instead, deeply worried about Margera. One fan commented: "Watching you self destruct is a jarring reminder to every delusional alcoholic/addict out there that we can ride this thing to the gates of insanity or death. And as a fan of yours I hope you have that moment of clarity before it’s too late."

He then spoke directly to the camera.

Margera discussed his upcoming plans to meet up with ex-Jackass director, Jeff Tremaine, and go to Comic-Con - but not before meeting a therapist, who was flying out from another state thanks to the nature of his meltdown.

Margera then shared more of his bizarre scrawlings.

One follower commented: "This post = psychosis induced ramblings. Someone’s gonna lock him up soon."

He next shared a terrifying flow chart.

Brandon Novak commented on this post: "I as well as every other name on ur list are actual “real friends" of yours who truly care about ur well being and quality of life. We WILL NOT condone ur fatal behaviors or justify ur actions in hopes of u not getting angry with us....... I refuse to high five u to ur grave!!!!! I love u and will do whatever it takes to help u so please fucking let me/us."

He tested his followers by sending them a message.

(For those who can't be bothered figuring it out, this one reads: "It is easy.")

He then went back to his Dr. Phil train of thought.

He first talked about his ex and the mother of his child, Nikki. He claims that she's using his eighteen-month-old baby as "bait" to prevent them from splitting up.

Margera then turns the target to his mother.

He captioned this video: "Dr. phil my mom invented a time machine so bam margera can go now where fast and talk in circles answering questions with questions."

Next, he turned on Brandon Novak once more.

He claimed that Novak uses his own sobriety to get one up on Margera. But one fan commented saying: "it’s sad to see you sitting in a hotel room, lonely that your friends aren’t helping you. But that’s because you reject our help. We are here for you, ready to offer the help, but you have to make the decision to accept it. You’re jealous of Novak’s sobriety to the point that you’re trying to destroy his reputation. But that’s not going to happen, because your fans see right through you. Do you want what he has? Do you want to lead a productive life of sobriety? Do you want your loving family back?"

He also claims that Novak isn't there for him anymore.

Although, as one commenter pointed out: "maybe he is afraid that if he hangs around with you, he will end up drinking again?"

He also made some pretty out-there claims about his ex-friend.

Margera said that Novak attempts to get people into rehab in order to earn a commission - although multiple commenters stood up for Novak and claimed that this isn't a thing.

Margera also criticizes commenters.

He claims that he's fed up with people telling him that he needs help, because he's asking for help - but only from Dr. Phil.

Many ex-Jackass cast members have reached out to offer help to Bam.

Including this heartfelt message from Steve-O, who, himself, has struggled with addiction and mental health issues over the years - but is now clean, sober, and living his best life.

It's also reported that relationships are on the mend.

According to reports, Bam's mom, April Margera, Skype called for a mediated conversation with Dr. Phil and her troubled son.

And that's not all.

It's claimed that Bam's estranged wife, Nikki Boyd, was actually on hand in person to speak to him and to encourage him to get help - at the very least, for the good of the pair's shared child, Phoenix Wolf.

Because it seems like Bam is still refusing help from those who love him most.

According to sources, he's still refusing to talk to his parents, and they're incredibly worried about their son.

April and Phil Margera also revealed the reason that they believe that Bam is in such a bad way.

They believe that Bam has stopped taking medication for his bipolar disorder, which is what's leading to these massive highs and lows of mood - and his manic outbursts.
