You're doing so well! I hope the massage does the trick and that your bike is ok.

I understand completely the sense of achievement at missing things, I was petrified to ride past a parked Porsche, and was as proud of not cycling into it as I was of the whole ride. I still struggle with riding past parked cars and signalling at the same time, but that will come with time and confidence. Starting off smoothly comes with time too, I wobbled all over the place three weeks back but can set off in quite a controlled way now. How brilliant that you're getting lessons twice a week, that will really help.
