Aubrey O’Day is out of the hospital and ready to talk about how watching the Diddy Netflix documentary re-traumatized her … making her so ill she had to skip a Danity Kane reunion show.

Aubrey tells TMZ … she was taken to the ER on Wednesday, experiencing “vertigo, fever, dizziness, migraine, chills and vomiting all night” — and she says it was all a result of watching 50 Cent‘s doc, in which she participated.

She tells us … “Watching everything from Netflix unfold publicly, seeing parts of a world I only knew from inside my own limited lens, was like living it again, but this time with context and truth outside of me. I didn’t think it would traumatize me the way it did, but watching the pieces line up from a distance outside of myself has felt like my nervous system was reliving everything with more clarity than I ever even asked for.”

Aubrey had to miss the Danity Kane reunion show, the L.A. stop on the group’s comeback tour. Aundrea Fimbres and D. Woods ended up performing as a duo at the El Rey Theatre.

AO says she’s hurt by comments from some people on Instagram, who said she needs to be tougher and should’ve done the show — having no idea the severity of her breakdown.

At one point in the doc, Aubrey reads a sexually charged email allegedly from Diddy … and said she believes she was fired from the “Making the Band 3” group because she refused his sexual advances.

She tells us … “My heart is broken because I never want to let my DK sisters or the fans down … However, I can’t wait to be with my girls for our Connecticut show on the 13th.”

Feel better, Aubrey!
