I'm about to start my VA paperwork for medical support and to inquire about housing loans. I'm really sorry about your troubles. I have tinnitus too, but in all my research I only found what I called habituation techniques for the malady.
My personal demons were spinal issues, cataracts, and Dupuytren's contracture. I start my second phase of radiation therapy tomorrow.
I don't know you, but I feel for you. I hope you can get to the place you need to go. Eventually, with planning and will, we will get there.
