Miley Cyrus is having a rough time in the hospital.

The singer was laid up Tuesday, reportedly for an allergic reaction to sinus medication, and canceled several tour dates.

She tweeted her frustration today (Thursday) and posted a selfie of herself looking sad. "Over the hospital. I miss #bangerztour. #5amhospyselfie so sleeeeepy #medztime" She also reference her deceased dog, adding, "#WishICouldCuddleFloyd #WhoJinxedMe."

In another tweet, she wrote, "Can’t quit crying. I wanna go back on tour. I'm meant to be onstage performing for y’all… not laying in a hospital bed."

She's not going back on stage anytime soon. She's postponed two more tour dates -- Friday's show in Nashville is now set for August 7th and Saturday's gig in Louisville will take place on August 9th.
