If you feel overwhelmed during the weekly review, it's because you really do have tons of stuff to deal with. That's good. It needs to feel overwhelming, so that you'll do something about it. Let yourself feel overwhelmed, then look at your work and ask how you can make it less overwhelming. What can you drop (for now)? Who can you talk to?
As Brent said in another thread, the overwhelming workload was always there. Skipping the weekly review doesn't make it go away, it just erodes your ability to deal with it.
