Brink sipped on some cranberry juice as she detailed it all ... even sharing her excitement to tune in to "Love Island" later in the night.

"Chillin on the road to recovery 🤍🦵🏻," Brink captioned her Instagram post. "thank you all for the well wishes:) I’m feeling extremely encouraged, supported & ready to make small strides everyday. #delayednotdenied."
