In the last week I've been too busy to be systematic about my progress. I didn't have time to stand waiting in the bathroom for someone to come by so I could try to pee.
But I didn't allow myself to regress either. I was lucky enough to find the bathroom occupied on more than one occasion a day and each time I used the stall with the door left open wide. Each time was a success but because it wasn't a progression of success through harder and harder situations I didn't get as much confidence from it as I had hoped. Oh for a pee-buddy!
But I am starting to think that I could move out of the stall into the urinal when there is nobody in the bathroom and wait at the urinal, trying to go when someone enters the room.
This will be a big challenge and I am afraid of slipping backwards but I think I can do it and I'm going to have to try at some point.
