If the symptoms go away with benzos, it seems that the source of your tinnitus is some form of generalised anxiety syndrome, with all the niceties that come with it: tension headaches, teeth clenching, TMJ disorder...
The burnout stresses were eased thanks to the pills, but once withdrawn came back probably harder which could have then triggered your tinnitus.
This is why benzos should never be prescribed without any other therapeutic approach alongside. They just hide the pain under the carpet for a while only to see it come back worse after and the root cause needs to be addressed with other means in the meantime.
Good luck with the road back to balance. There's no secret remedy and it's probably best to take a holistic approach for it and work on your well being from multiple fronts.
