8:30 AM PT -- 7/15 -- Conor McGregor is addressing his fans for the first time since leaving an L.A. hospital Wednesday afternoon ... updating his fans on his health just days after breaking his leg, and having extensive surgery to repair the injury.
McGregor admits he's been on a roller coaster of emotions since the gruesome injury occurred ... sometimes feeling "euphoric" -- and other times feeling down in the dumps and in pain.
Conor says the broken leg wasn't Poirier's doing ... McGregor says he had previous injuries -- "multiple stress fractures" -- that led to the nasty break.
The Notorious also says the broken leg bones will actually end up being an advantage when he returns to the Octagon ... 'cause the "unbreakable" titanium rod is staying put in his leg.
"I'm like Arnie in Terminator 2!"
That makes Dustin ... T-1000??
Conor McGregorwas released from a Los Angeles hospital ... just days after surgeons used a rod, plate and screws to fix The Notorious' broken leg.
TMZ Sports talked to Dana White ... who updated us on McGregor's status.
"I think they just released him right now from the hospital about 10, 15 minutes ago."
