So earlier today I had a little bit of a nervous breakdown, which has me completely freaked out since I'm the first person I personally know to have anything like this happen (my entire family is some of the most psychologically stable people that I know of). I ended up spending about 30-45 minutes in the corner of my bedroom shaking uncontrollably, complete with difficulty breathing, my hands cramping into fists (I literally could not open them), and paresthesia (pins&needles) all over my face and arms. I was only able to break out of it with the breathing exercises that I learned as a musician, and I have no doubt that if I was any less of a person I would probably still be there right now.
Basically the main stress is my scholarship/GPA interaction. I just found out a few weeks ago that my current GPA is 2.97, but the scholarship that gives me free tuition needs a 3.0 to be refreshed. With my current class grades I should barely scrape by the cutoff but it all depends on how well I do on my finals (which are the week after next). Quite a few of my class grades depend heavily on doing "good" on the final (not "average"; "good", preferably "very good"). And since I've always had a problem forcing myself to do "busy work" that teachers give out when I already understand the concepts, many of my classes have very small safety nets for me to land in if I mess up.
As you can imagine I'm pretty stressed out about this, especially since I get along great with my parents and really don't want to have to go to them and say "Yeah I just cost you guys $20,000 through my inability to force myself to do 'busy work'." (Doubly so since right now they are also the ones paying for my housing, food, and gas. My usual comeback when my mom mentions this is that I'm saving them $10,000 a year with the scholarship.) Right now I'm studying all I can to do well and grasping every bit of extra credit I can find, but it still has me really terrified that I'm stressed enough to breakdown like that in the first place.
