I’m so scared

Hi, I'm 19F and I think I might have tinnitus. The doctor didn't give me a diagnosis vocally but it does say that on my after visit summary, but it all started two days ago. I woke up feeling dizzy and lightheaded, and a few seconds later, I completely lost hearing in my left ear. I hear white noise, but not in an annoying way; it's mostly just annoying because it feels like my ear needs to pop. I'm so scared because I fell down the rabbit hole of tinnitus research, and it's not 100% sure I'll get better soon. I'm genuinely terrified. I'm asking for advice on how to deal with this issue. By the way, I did get referred to an ENT, but I'm not 100% sure how quickly they'll see me.
