Seriously, I'm dying here!

I needed a higher level of math than what I had to access university, so I thought "I'll take math as a summer class. How bad can it be?" The answer: Very bad!
I don't think I've ever experienced something as energy draining as this in my life. 7 hours straight of math 5 days a week, plus the homework and various assignments
I've only been at it for four days, and I've already had two times where I told myself that this couldn't posibly be worth it and that I just wanted to quit.

But I only have to endure it for 1 1/2 month - then it'll all be over; if I pass, that is...
I think I'm in dire need of a miracle to make this. If anyone knows where to get or buys those, let me know.
