Bathroom light fell out of the ceiling. Can I fix this myself?

I don't know much about these things, so apologies in advance for vague terms or if I'm misunderstanding the situation.

I was trying to change the light in my bathroom and accidentally ripped the thing out of the ceiling. I opened up the lamp in an attempt to screw it back into place, but it seems the holes widened when the light fell out. So far I haven't been able to find out what I should be doing, or what can be done without calling someone. Pics are the underside of the light, the fallen light itself, and what it should look like. Would like to take care of this ASAP so I don't get mold up there, so any advice is appreciated.

Two or Three 5mm Spring toggles would hold the base back up, as for the wiring part hard to tell but be carefull as may be Live still even with the light switch off.

I would advise you leave it to a pro to fix it
