I've had Tinnitus for a few years now, it's a high pitched 24/7 ringing that I can pretty much tune out during the day when stuff is going on, but once it's all quiet, I really notice it.
I've been trying to avoid loud noises at all costs, but despite that, it actually got a little worse in the last couple of months.
What really scares me is that I'm almost 34 now and I have it like this, I just fear that as I get older, it's gonna start to drown out all other sounds and it'll be all I can hear. I think at that point, I'll end up killing myself, ha ha.
There is a foundation for Tinnitus, I even joined it and make donations from time to time -
