Doing a quick burst of exercise seems to help. Yes, news just in, exercise can help relieve anxiety and stress shocker!
I just forced myself to dance (more like running on the spot but who cares) as hard as I could for 4 minutes to an uptempo song and the physical feeling of exhaustion has almost totally overriden the anxiety feeling. I could have gone out and did the walk around the block like last night but going outside gives me anxiety too so yeah I tried this instead.
The anxiety is still there but the physical pit of doom is lessened. Result!
