Thank you for your concern. At least you can still protect your ears in the future. There are high quality earplugs that don't muffle sound: https://www.amazon.com/Etymotic-Research-High-Fidelity-Earplugs-Standard/dp/B00G0PPTAK>>406
I've had it for my entire life, however a recent motorsport event a few months ago aggravated it to the point of it being very noticeable. I didn't have access to hearing protection at the time.

I've had tinnitus really bad for most of my life and it's just one of those things you get used to. It's like living under power-lines, the sound is annoying, and you feel like you'll never get used to it, but eventually it just becomes the standard background noise to life and you don't really notice it. Just try your best to not think about it and eventually it wont bug you. Hopefully you get used to it quickly!
I've heard from several people that the white/pink/brown noise generators on https://mynoise.net/
can help alleviate tinnitus for a while. If it's more of a pulsing ring, maybe sine waves can also help.
