Aaron Carter: Out of Rehab and 30 Pounds Heavier!

Just when you thought 2017 couldn't get more eventful for Aaron Carter ...

Wishful thinking, huh?

Throughout this year -- specifically these past few months -- Aaron has seemed to be on a terrifying downward spiral.

So terrifying that when he made an appearance on The Doctors last month, those doctors advised him that if he didn't go to rehab to get his drug use sorted, he'd die.

His problems began (or at least we learned of the severity of his problems) in July, when he was arrested for a DUI and drug possession.

He and his then-girlfriend, Madison Parker, had marijuana on them, and he was seen driving erratically, though he did refuse testing at the time of his arrest.

After that, he felt the need to defend himself against what he said were false accusations, which resulted in an extremely emotional interview in which he revealed he suffers from an eating disorder and hates his appearance.

Then in September, he was visited by police four times in less than two days.

The visits were for welfare checks, as people close to Aaron had called in to report that he may be a danger to himself or others.

A couple of weeks later, police were called to his home again, and though we never heard many details on that visit, it seems to have been yet another welfare check.

Luckily, something seemed to click then for Aaron -- after that, he went off to rehab.

In a series of tweets he made just before checking in for treatment, he explained that "this year has been crazy and I need some time off from it all."

"Going to get strong," he wrote, "and deal with my stress conditions and get better."

He said that he'd be gone for "a while," and that he didn't plan on returning to social media until 2018 at the earliest.

But he's baaaaaaack!

Yep, after just two weeks of treatment, Aaron is back at home.

And though that may be a little concerning -- two weeks doesn't sound like nearly long enough to address whatever it was that was troubling him -- at least one good thing has come from his short time away.

Check out this transformation:

For the past few years, Aaron has gotten a whole lot of hate for his appearance. He was very thin, and lots of people speculated that his size was due to drug use.

He's insisted that he's thin because of a hiatal hernia that makes it difficult to eat, in addition to that eating disorder we already discussed.

But now he says he's gone "from 115 to 145 in just three weeks" because he "needed some time to heal."

He gained 30 pounds in three weeks, and he seems pretty pleased about it!

"Thank you to everyone who has continued to believe in me and stick by my side," he tweeted after sharing the photo. "I will always aim to make you proud but this was for me."

It also looks like he got his appetite back -- he shared this photo of himself and asked "What's for dinner? I'll make both":

As for his abrupt departure from rehab, his rep made a statement explaining that "Several legal and personal matters arose that required his immediate in person attention."

"He is still very much committed to his wellness and will be continually working toward being the best possible person."

We hope for his sake that that's the case.

After the year he's had, Aaron Carter sure could use a win.
