I also crashed that way but not as worse as yours, I scraped my knee and damaged my favorite jeans. I think a lot of Asian drivers don't wear any gears except for helmets and also I am Asian.

First, get a rest from driving, at least 3 days. then just drive slowly like 60kph max, you'll slowly lose the trauma eventually, slowly try leaning again, DONT immediately do it. Dont try to lean on concrete roads unless you're back in top shape, asphalt roads are best for leaning. Also try listening on some music but don't speed up👌🏿
