Kehlani posted the ordeal on Instagram -- showing a pic of herself with an IV in her arm in a hospital bed with the caption, "I wanted to leave this earth. Being completely selfish for once. Never thought I'd get to such a low point."
FYI -- The Internet was brutal to Kehlani yesterday over a picture that suggested she cheated on Irving with her singer ex-boyfriend "PartyNextDoor."
But Kehlani says SHE NEVER CHEATED -- and says she was already broken up with Irving when she got back together with "PND."
"I am severely utterly in love with my first love.
