Fortunately, this is perhaps the one shooting situation anyone will ever encounter where recoil is a complete non-issue: by the time you experience any recoil the bullet will already have done its work and you will already be dead.
Far more important is to avoid what shooters call "flinch", which is when you anticipate the shock of the discharge and preemptively pull the gun off target as you pull the trigger. One thing that helps you avoid this is to have a light trigger pull. To that end, can you cock your revolver so that it functions as a single action? Trigger pull is much lighter for a single action than for a double action, and "flinch" will not be as much of a problem.
The other factor working in your favor, to counteract "flinch", is that "flinching" typically pulls the aim of the gun down. If you aim at the brainstem but miss low, you're very likely to hit the spinal cord, which will be just as effective at killing you.
