NC for this as very embarrassed.
Yesterday I was an enforced situation where I was not able to go to the loo, despite needing desperately.
Four hours later when I finally got into the same room as one I didn't make it 
I'm now having real trouble holding my water - going every hour or so, which is far more than normal for me - and finding I'm desperate with even the slightest bladder pressure (ie I'm going from nothing to desperate in seconds)
Please tell me this is all psychological after yesterday and that it will get better!
