Good news that your largely OK and so is the bike. Aftermarket clutch levers are cheap. Still....
Ouch and more ouch. I've been down and broken 2 ribs twice... never 6. It must hurt like #@!#$$%^& to breathe. I've also had a shoulder separation with surgery, but I don't remember very much pain except for the road rash which DID.
Locking up the front wheel is not usual. Just wondering what kind of front tire you are running?
I've been at the biking thing for many decades. I've found that where ever there is heavy traffic there are places where cars/trucks are backed up at traffic lights and bottlenect exits for multilane highways. There are many old vehicles that drip oil onto the pavement while stopped in these lineups. The pavement becomes slick and the rest you likely know. It is particularly bad with a light rain to emulsify the oil. I dam near 'stuffed it', on a multilane exit where there were chronic exit backups. My luck was better and I went down between the cars and guard rail for at least 3 cars. I was riding a, (now), ancient Ducatti which for all of its legion of faults... was incredibly manouverable. I've found other such intersections/traffic lights since then.
Don't give it up. It's worth fighting for.
