I can't say for sure, Danish Girl. But maybe you have Visual Snow Syndrome? Floaters and other such disturbances are common symptoms.You are right about that. I want to try my best to find just a tad bit of enjoyment during these utter miserable days whether being able to gather my thoughts and read a book maybe 15 minutes, a good meal, watching a good movie (with the sound on very low volume). I just feel I fall short at this point... it's so hard this life. It's so inhumanely hard!
Maybe check out The Visual Snow Initiative? They have a series of videos that have helped people reduce their symptoms. It won't do anything for your tinnitus or hyperacusis, and it doesn't help everyone, but I truly think they're a good organization dedicated to their cause.
I wish I could do more for you.
