Mitral valve & possible aorta replacement

Hi everyone I’m a 33 yr old female, I’m having surgery next week, I’m hoping to have my mitral valve repaired instead of replaced & the doctor mentioned possibly replacing the aorta as well if need be. I choose mechanical valve for both, pretty nervous. Has anyone had both replaced and done the mechanical? Any advice/tips or things you wish you knew before hand?
Do you experience the clicking sound, does it go away?
-how long were you in the hospital
-how long did it take you to fully recover
-what would you say the most painful part was?
Thanks 😊
