I think I might have ruined my life

I have always listened to music but over the past 2 years, I have become too obsessed with it. So obsessed to the point where I have been listening to music for at least 7-8 hours every single day usually at above 65% volume,

and now its coming back to haunt me.

For 7 months now, my left ear has felt muffled and it has only become worse so because of that, I have now stopped plugging my earphones in my left ear and started to use my right ear but I still occassionally used my left ear when I wanted to listen to music in both my ears at a loud volume.

I should had stopped and taken more caution with my ears but I didn't so 2 days ago, I suddenly noticed a 'EEEE' kind of noise in my left ear and my mind instantly went towards tinnitus because I've read so much about it while researching about my muffled ears problem. the noise is loud but manageable for the most part. I have heard that tinnitus rarely ever goes away and that there is no cure so my fear is that, as I age then the noise is only going to get louder and more annoying. I already have other health problems so this might just ruin my life.

The nosie is only in my left ear because thats the only ear I used the mostto listen to music in, sometimes it switches to my right ear but for the most part, its in my left ear only.

I'm scheduled to visit the doctor tomorrow, I hope its not tinnitus. my left ear is still muffled so the sound could be because of ear wax. I'll have to see. I just needed a place where I could vet. do you guys think it could be tinnitus or something else?
