Got any Y shaped cracked in ceiling? That's a bad sign.
Ceiling needs overboarding and skim.
Hire board lifter for a week and plasterboard over with 50mm drywall screws.
I don't recommend patching.
To patch brush some Sbr around edges and blob sone plaster around to firm up before more falls.
Cut plasterboard to fit and fix
Bonding and skim.
I wouldn't though.
