This may not be of great comfort, but remember ol’ Beethoven worked completely deaf towards the end. I too have damaged my ears, but I keep up a network of friends who have better ears, and when I am in doubt, I seek their critique… hey, there’s lots of that around here too. NO way am I giving this up for a long time to come.
Just keep on going, no need to toss in the towel . 
And I’ve kept on preaching to the kids about ear-buds… we’re gonna have a $hitload of deafies in 20 years.
p.s. protect what’s left - I use ear protection when using the lawn mower, power tools, vacuum cleaner, etc.
