I'll trade you lives.
Mind, mine comes with extra perks, such as chronic pain, abject poverty and being tortured by my roommate every Sunday morning with the horrors of the stench of fresh baked goods (cookies and cakes).

Reality is that a person cannot endure constant unrelieved stress for long periods of time.
Read
this article and pay special attention to the list of symptoms. If you are displaying these symptoms then it may be time for you to seriously reconsider what it is your doing and try to figure out how to cut down on the demands on your system. One (perhaps the best) option is to reduce your class load and aim to stretch it out over a bit more time in order to maintain the job.
As for buying a car. I don't know the car, I can't kick its tires, test drive it, listen to the motor, I don't even know how many miles it has. So I can't tell you if 5K for it is a good deal or a bad deal. However $5k for a 2009 car that is in good condition is about right, falls well within the nominal parameters of 'value'.
One thing you can do is check with insurance companies and see what their 'totaled' estimate is for that make, model and year. The 'totaled' value - meaning how much damage the car can sustain and insurance not covering it, closely relates to is depreciating value over time. Thus if the insurance company covers $4500-$5500 on that year,make and model you know that the outlay cost of $5k is about right.
Kelley Blue Book is where insurance companies go to find the 'value' of a car for this year.
There is also
CarFax which is supposed to report on the vehicles history. I assume based on insurance claims made against it. This is all fine and well, but there is always a chance that a car was totaled and no claim was made and someone paid out of pocket for the damages. Not that bad if its only body damage, a potential road hazard nightmare if the frame got bent.
Lastly, take time to remind yourself to breath.
