This is Dr. David
this can be a very difficult situation if you are stuck in the VA system and if your insurance will not pay for you to see another doctor or psychiatrist.
at your age of 70, you should also be able to have medicare federal insurance which can allow you to see doctors outside of the VA system
you may need to get a secondary insurance to cover the 20% Medicare doesn't pay for.
if you have this, you can leave the VA and find another psychiatrist or primary care doctor outside of the VA system
so you don't have to keep seeing this abusive doctor at the VA
