I developed electric crickets in my left year about 8-9 years ago now, it’s not tinnitus because it’s not the little hairs in my ears it’s the nerve between my ear and brain shorting out but the result is the same - when I had my hearing tested they told me 3 months is the time most people either start being able to ignore it OR need supportive care, they offered someone to talk to and/or antidepressants if I hadn’t adjusted in 3 months, thankfully I did and I can tune it out, or tune in if I’m trying to sleep I can just listen to it and I fall asleep.

I would talk to your doctor, if you haven’t already, for the physical aspect of it and mention to them you’re struggling mentally with it, it’s SUPER common to the point my doctors were addressing it preemptively so they might be able to give you tools to help make things easier.
