Where are you up to old friend? I'm struggling at the minute, a variety of other health issues like you and no real tinnitus improvement. How you managing to cope?
This is not advice, just my personal experience: going part-time at work was the best decision. With tinnitus, there is no "Powering through". Not possible. Full time no longer an option. Not a loss I grieve, I have to obey my limitations. This feels right for me. Not saying it's right for anyone else but my personal story.
But, damn, I miss the desert, beach, and mountains
