Yesterday I dropped my phone in the toilet, I got it out and dried and and everything but didn’t turn it off later that day my volume on my phone kept going up and down by itself and last night I let it charge and I woke up this morning to turn it on and the screen keeps showing the apple logo then going black.

Take it to a reputable phone repair shop for liquid damage evaluation. It will require micro-soldering experience to fix liquid damaged phones so better take it to people that work on these daily especially if you need the information off the phone.
