I feel like crap

I'm sick. I'm pretty sure it's just a cold but I don't have Campbell's chicken noodle soup nor my mommy so it sucks pretty bad.
The sore throat started Tuesday night so I got some herbal tea to drink while I did my homework. Then Wednesday I felt pretty bad and my voice was pretty soft so I called in sick to work and class. By the end of the night I was feeling worse but I had been drinking water all day, staying inside, and even resting my voice.
This morning I sleep through my alarm and through my Chinese class (receiving a text from my teacher about it). I then tried talking and my voice was not only soft but going in and out. So I text Marketus looking for advice on what to do.
Normally I would have just said "hey I don't feel well but I think it's just a cold;" however, tomorrow my group is supposed to go to Qing Hai. I don't know exactly where it is but it's at a higher altitude which means breathing is going to be difficult which means a girl with asthma and a cold has something to worry about. He made a doctor appointment in the city for me and asked Xiao Zhang (I think I have her name right) to escort me.
I just got back and basically he said it was a cold and just to rest. That's when I brought up Qing Hai and how they want to know if I can go and what not. He goes "Do you have to?"
"No, I don't think so."
"Then you shouldn't. If something happens it will be very difficult for you to receive medical treatment."
He was Chinese but his English was good. He wrote a note explaining my situation and even told Xiao Zhang.
Honestly? Right now I don't want to go anywhere. I just want to stay in my dorm and rest. Last week though I was definitely looking forward to the trip! I mean, it seemed like we were going to be really roughing it (he gave us sleeping bags!) and experience "real China." The only thing that worried me was the high altitude (mostly because Marketus was making such a big deal about it). But on top of experiencing "real China" this might be the only vacation I get to take! We have a week of independent travel but I'm pretty sure I can't afford to go anywhere which means this would have been my one chance to get out of Beijing.
Marketus said to tell him how I'm feeling before class tomorrow and we'll go from there.
