Her tweet is gone, her twitter is private. Thousands of people are laughing AT HER and laughing WITH BRANDON. That's about as roasted as it gets. There's no rules to jokes man. I understand if you think it's "too dark" or it "goes too far" or it "punches below the belt", but that doesn't mean it's not a joke, just because you personally didn't enjoy it.
It will get better my friend! Do not lose hope and stay positive! Just being alive during a time like this is a privilege. Sorry I don't have any better advice, but I'm sure the comments will be filled with some!
