I guess I’m a part of the club now

Hello, 24m here, woke up yesterday morning thinking there’s something wrong with the electronics in my room because I could hear a loud high frequency pitch.

Turns out it’s in my head, couldn’t sleep at night because it kept getting louder to the point I was experiencing nausea, my anxiety spiking didn’t help either.
Going to visit an ENT today, I had a cracking pain randomly in my left ear a week back, maybe there is other reasons?

I hope, so that maybe it can be treated, but deep down I feel like it’s here to stay. Will keep you guys updated, I listened to a man walking me through on yt to fall asleep last night since nothing else seem to drown out the noise.
