i rode into a car today, how can i move on from it?

i was at a junction and i looked left and right and there were no cars, so i pulled out then next thing i know a car is infront of me?! it was crazy, but im okay and my bikes fine. i have a graze on my arm but im not going to let that ruin my day.

i dont really know how i can move on from it? has it happened to anybody else or anything similar and if so how did you get over it? because i do enjoy cycling i just dont want to stop doing it because of a stupid mistake i think i made.
