Depressed

So I'm back at CMU and things are starting to pick up again. I started with eight classes, but after attending one of them (a StuCO) and realized that for a dance class it was sort of a joke, I am now down to seven. In studio, they immediately tossed us into a five day charette that I actually decided to give a shit about and am, yet again, met with disappointment - which, of course, is my cue to slack off for the semester.
To continue, the doctors tell me that there's something wrong with me so I have to get a second opinion tomorrow and apparently it involves getting a biopsy and spending a lot of money. Mom and I doubt the school health center made a correct diagnosis, but whatever.
Then there's the fact that I had high hopes about getting to spend lots of time with my Benny-bean, and that doesn't seem to be the case, what with dance and Lunar Gala and all the work I have to do. It's only been a week and I've already pulled two all-nighters.
People have also been bitching in studio about the fact that I complain all the time, but mostly it's due to the above several reasons. The anxiety that I might be seriously sick just eats away at a person. I really doubt it's anything, but still, you never know.
Yesterday I had dance auditions and I completely screwed up. My brain was completely clogged so I couldn't really learn the dance. I've never had so much trouble learning a dance, not since ninth grade. I might have gotten into one dance, but yet again, I doubt it's one I really want to be in.
And now one of my classmates is talking about how wonderful his project is and even though I want to be gracious and all that crap, I'm feeling really down about how I can't ever seem to get anything right and I wonder if I should just give up and go and do engineering even though I'll be depressed for the rest of my life.
It's been overall a pretty crappy week.
On the upside, Ben's brother had a baby and we went and got to see her. We were there for three hours and she wouldn't wake up, but she was still absolutely adorable and tiny!
