New Diagnosis: I have hearing loss in both ears.

I have hearing loss in both ears. Constant high pitch constant ringing. Annoying. I am debating what to do. I don't know if it's depression meds I am on or related to RA or OA or Huntington Corea. I have 4 more docs to go on each issue including loss of balance. It just hit me all at once. I do have long Covid. The expense is what is making me double think what to do. Disability doesn't go far but if I don't help it I am told dementia could set it. I already have short term memory loss from long covid. I need to know more. Plus I am a widow so on my own. I need your feedback on what I am facing.
