Sorry to heart about your loss, BUT
You mention that this is a relative recent injury. Give it some time before you give up on everything. Physical trauma is often just temporary. You might even give it a year or two. I hate to see anyone give up on the beauty of Music/sound.
Also there are different types of tinnitus and how it affects a persons hearing. I suffer from years of live concerts up close and personal with the huge bass horns, Jet engines from my time in the Navy, and gun fire W/O proper hearing protection, and though my Tinnitus is getting worse now at the age of 71, and my level of auditory volume is probably 60% or more, I still hear the music clearly and can enjoy it fully.
DON"T GIVE UP!
