Britney Spears wishes online trolls knew how "severe [her] sadness" is

She wrote on Instagram: "Another excursion but this time a smaller boat !!! Honestly, I like the smaller one way better. I took the video of myself dancing down because so many people said so many mean things... if they only knew how severe my sadness is. It is a f******miracle from God that I played and danced, period. It is insane!!!

"I didn't think I was gonna go at all I was that sad... but immediately I saw the ocean, the small little hotel that looks like an apartment, and the breakfast table inside the pool !!! I'm such a strange cookie I guess most artists are a little weird, but I immediately got busy and played with dark music and Winehouse with black lace and red bottoms !!!

"I forgot I did any of that and when I got home last night and was like WTF !!! I took all my work down then of course I looked through my phone and was like Damn, there's so much I haven't even shown but it saddens me people say mean things about me."

The '...Baby One More Time' hitmaker continued her rant by noting that she is "so damn sick" of others faking "concern" for her before revealing that she has been fasting all week and had just enjoyed a bacon cheeseburger.

She added: "I'm so damn sick of people saying they are concerned and if you don't like the way I move, f*** off and don't watch it !!! After my week of fasting, I sat down to finally have my bacon cheeseburger with a bun that's so high it looked like a pie and right when I cut it in half right down the middle I saw the white Swiss cheese and my mouth watered. And then when the bacon, which is never chewy always crispy, hits my tongue and the meat !!! Food gives me a high, like feeling 6 years old because food is god, especially if you fast like me. It's honestly better than sex!"
