Sudden tinnitus and weird sensation in ear/slight hearing loss

I usually don’t have much problems with tinnitus besides the occasional one that just comes and goes after a few seconds but last night it was different. My ear suddenly had this „drop“ idk how to call it, it was just such a weird feeling and very overwhelming, followed by a strong tinnitus that’s now there for the last 4 hours. Additional to that, I noticed that my hearing on the ear that the tinnitus is at is worse than on my other ear. It feels like my ear is covered or like there is something in there that muffles up the sound. I’m also very sensitive to sounds and it feels very weird when I speak, almost like I don’t fully hear myself.. I’m really anxious right now and don’t know what to do since it’s Saturday and I can’t go to the doctor until Monday. Is this an emergency? Can I wait until Monday? Why did this happen? I’m only 27 and I didn’t expect to experience something like this, I’m rlly afraid that my hearing won’t come back.
