I have had tinnitus for most of my life. When I was a child I had a massive ear infection that burst my eardrum on the left side and that is the worse side. Honestly I can just tune it out and it seems normal. It mainly causes issues in louder environments because it can be difficult to hear what people are saying. And it doesn’t need to be very loud. A bar with music and lots of people talking around me can be enough.
It is totally possible to exist with it though.
