I felt 1000times to talk to a lawyer from my medical mistreatment causing tinnitus.... but I just gave a bad google review.Your legal situation sounds relatively simple, insofar as it doesn't sound like there's anything you can do. Your spiritual situation is much harder and thornier, but my intuition is that spending time actively wishing malice and harm on others, even those who "deserve" it, is not helping you.
Nights when I can't sleep I always think why did I go to that doctor. Why did I let her pour peroxide in ear.... i can't take my decision when I said ok to pour that back or can i revisit that day where I was laughing like a child after work and was ready to go home.... why did I drive to the physician and not wait for ENT.... I think replay the events of that day till day its been 4months.
I am trying my best to forgive people responsible for my tinnitus and live my life laughter and peace.
Your answer had given me a bit of solace.
