Hearing Disorders, wrong response in left ear or both.

Hi, I'm having a really difficult situation now, recently I've been listening to loud music or maybe the sound is not right for my ears. the next day I woke up,
every instruments from any speakers to any devices sound different.
for example :
I'm listening to a grand piano sound what i hear with my left ear it sounds like broken piano and it sounds normal with my right ear (grandpiano). both of my ears are responding differently...

so what i mean is. whatever I listen to is all out pitched, it doesnt sounds like what it supposed to sounds like. basically my left ear is hearing everything in outpitched mode and my right ear is functioning properly.
I'm really worried, its been 3 days. I need advices.. my parents doesnt want me to see a doctor. so I need y'all answers. please and thank you :)

See your doctor, but if they can't figure out what's wrong immediately, get a hearing test from an audiologist. Don't wait, do it as soon as you can.
