Thank you so much for your advice everyone
I've just had the best commute ever
I now know exactly where I went wrong yesterday. I took the wrong turn again today but quickly realised my mistake and got off my bike and crossed the road and took the right turn
After that, the ride couldn't have been smoother. I also noticed that drivers gave me a lot more space today. The only reason I can think is that I was wearing a nice pretty flowery backpack
Anyway I'm feeling extremely confident right now thanks to everyone here. I can't wait for my ride home
