Bulshit happening, my phone hates me

My SD card randomly disconnected after I restarted my phone cuz some apps were taking too long to load, my friend said my SD card might be corrupted which well that SD card contains a lot of music (the entire Linkin Park collection from the existence of Grey Daze to 2017, yk why it ends there, and some other music too, it adds up a lot, I might have some other things on it too) just I'm currently anxious as fuck, my friend suggested I use a computer open file explorer and delete anything suspicious, and back up the files tho a little problem, I do not possess a computer and the only one is my mothers computer which I regularly don't have access to it since it's not mine, so I'm left with waiting for my mother to get home to solve this bulshit so I have to wait for 2 hours, in the meantime I almost had a mental breakdown, ig that's my rant I come here once every blue moon (currently too busy with school, I'm too busy learning about metal materials) maybe I'm just a lobotom
