I didn't comment on your broken glass analogy--with missing pieces--so apt.
It's tough when you are isolated. And even more so & understandable if sounds bother you. Has the tinnitus improved some?
And if you found a horse therapy person, even w/o knowledge of LD, it might be good to have just a kind soul to share some of your thoughts, wouldn't it?
The broken glass reminded me of the cracked pot story. Yes, I'm calling you a crackpot (!), but from one crackpot to another! :)
