Well, are you alright? Any bad bruises or road rash? I've been having a bad 2 weeks, with three accidents. Luckily nothing too destructive on my bike (though I did smash up my friend's crank pretty bad in one pile up), but I have so much road rash. I hate that stuff.
If you'd like I could send you a brake and lever for your next build! Don't ride without a front brake. Even with a coaster brake it's as dangerous as a brakeless fixie.
