I've had tinnitus for a few years now and I've noticed I go through episodes of the ringing getting worse. When I first got tinnitus it was so loud I couldn't focus, sleep, or hear anything else.
Currently when my episodes hit I go through the same thing; loud as fuck and unrelenting. For me it was anxiety that made my suffering unbearable and once I worked on that, with that understanding, I could deal with the episodes much easier.
These days I always come out of the episodes fine and life goes back to normal. 98% of the year I'm completely unaware I have tinnitus because I don't notice it anymore.
I have tips on dealing with tinnitus if interested. Learning to cope was the best I could do and it worked fabulously.
Things that helped:
Find noises that help mask your tinnitus. For me it was rushing water or specifically a running shower. I then downloaded an app called "relief resound" that is designed for people with tinnitus. I setup a rushing river sound and would play that at night to help me sleep. The sounds from my phone acted more as a distraction for my brain to focus on something else other than the tinnitus. After a few weeks of doing that sleeping became less stressful and even easy. I also found some sleepy bed time stories on Youtube that helped distract me as I feel asleep.
Changed my thinking. I would remind myself that my real issues wasn't tinnitus but my fear of hearing it, not escaping it, and general anxiety around it. I would constantly remind myself it's okay to hear it and to slowly practice focusing on new sounds like a show/movie I was currently watching or music. After a month or two my anxiety over it subsided and I was more accepting of my new reality and it didn't feel as scary anymore.
Developed patience. I figured getting accustomed to tinnitus would take some time so I took it slow and let myself not feel pressured (and more anxious). This helped me keep positive when hope was slipping for me. I still had episodes but patience let me deal with it and eventually come out on top.
Find a tinnitus buddy. I had an IRL friend who had tinnitus worse than me. It was incredibly therapeutic to talk to this person and discuss my fears. They informed me how they dealt with it and this gave me hope along with new ideas of overcoming it. It was really an aha moment for me to see someone not only "dealing" with tinnitus but actually living their life normally and not caring about it that turned everything around for me.
All these things in combination helped me cope and accept my new screaming ears. I can now sleep, don't really notice it, and have gone back to living my life like pre tinnitus. I was really really hopeless at one point but kept fighting at it and I'm very happy I did. Chronic issues can be really scary but attitude can change everything for the better.
