I've fallen on hard times, credit score has plummeted

Long story short in the last 4 months I've had a lot of hard issues come up..truck broke down, hospital bills etc and I've got 3 credit cards limited out at around $3,200 along with 35k of school debt. Score went from 680 to 580 within a matter of months...and I need to get a new car to boot and won't have the credit score to get approved for one..how do I go about fixing up my credit score? Some steps I can take? Not saying it will be a short process but I do not have a lot of credit history either so maybe it isn't the end of the world, but definitely a wake up call as I am young..


Thanks for any responses
