Mackenzie McKee has some seriously tragic news for us this weekend.
Back in January, as you may recall, the Teen Mom 3 star announced that her mother, Angie Douthit, had been diagnosed with stage four brain and lung cancer.
The family started a GoFundMe account to help cover medical costs, and in the description for the fundraiser they explained that she had tumors that "cover almost the entire brain," and that she had several masses in her lungs.
The diagnosis was especially shocking because Angie's always been very healthy -- she never smoked, she didn't drink, she ran marathons.
Mackenzie said at the time that she'd went to the doctor because she thought she had bronchitis.
In the months since her diagnosis, Angie has been going strong.
She's been giving some inspirational speeches and spending lots of time with family, judging by Mackenzie's Instagram post.
But now, in another post, we have a new update on how she's doing.
And unfortunately, it's bad news.
"O mom, you are so amazing," Mackenzie begins her post. "Idk how you are touching lives all around the world of people who have never met you but you are."
"You have such a strong message to share and you are not scared to shout it to the rooftops."
"You don't deserve this, none of it," she continues. "So happy, so healthy, and so faithful to God."
"Stage four cancer in your lungs, in your brain, and now in your bones. And not once have you questioned Gods love for you."
Yep, you read that right -- now, in addition to the brain cancer and the lung cancer, Angie also has cancer in her bones.
Mackenzie goes on to explain that they just got the bad news a few days ago, and that this whole nightmare has been "exhausting and expensive."
So to help with some of the costs, she's asking her fans to consider purchasing one of her "fitness at home workout programs," the workout and nutrition guides she sells on her site, Body by Mac
To her mother, Mac writes "One thing you wish people would do is to remain healthy and to #alwaysbekind. You helped me with my #bodybymac 3 month program and have always been my number one cheerleader through this all."
And so this weekend, if you buy one of her programs, all that money "will go towards the cost of all travel expenses and medication because you're so good and telling people to stop complaining, get off their butts, and get active."
"So here is to donating and getting healthy at the same time."
It's definitely a sweet gesture, and it really seems like Mackenzie is doing everything in her power to help her mother right now.
Remember, although we know who she is and although she starred on an MTV show, Teen Mom 3 only got one season before it was canceled, and that was back in 2013.
We know that the moms' salaries get increased every season, and that when the shows started out, they didn't make too much at all, considering.
For reference, Briana DeJesus reportedly made $20,000 for her first season of Teen Mom 2, which isn't a lot, considering the other moms brought in around $300,000.
Add in those three kids of hers, and there's a good chance that Mackenzie doesn't have any of her MTV money left, and that she's trying to capitalize on the fame she has with her workout programs.
We can't blame her for that, and if she's also using that fame to try to get donations to help her mother?
We certainly can't blame her for that either.
Honestly, Angie's prognosis doesn't sound good, but it's clear that she's still in good spirits, and that really is amazing.
So let's all send our best wishes to this family, OK?
