Would it be hard to come off diazepam 8mg after 35 years. I am trying it with my dr supervision and he agreed it is impossible thanks?

Not impossible. No, it's not impossible to come off valium after 35 years -- but it will need to be very gradual. Also, you'll need other methods of managing your anxiety. I suggest finding ; working with a good psychotherapist who knows cognitive behavioral therapy and mindfulness training. The 2 combined can be extremely effective in long-standing anxiety.
