Just a random little health question?

Ok, so I've been sick lately and I never usually get sick. Earlier this semester (college) I developed sypmtoms that kind of go with the flu. I had a really bad headache, phlegm, fever and cold flashes, muscle soreness. When that all went away a few days later my sore throat and phlegm stayed around. I noticed bumps in the back of my throat. Now it feels like I have water in my inner ears and can't concentrate worth crap. When I try to study now, my neck starts hurting really bad and I get headaches and eye aches. I need to get new gles, and have all 4 wisdom teeth pulled. Could these be why I've been feeling crappy. Now, I don't know if that has anything to do with this but, I've noticed that when I pee its really concentrated and smells like popcorn. It even foams (protein). Could any of this be caused by stress? I had my period a week and a half late and it was dark and had clots and almost brownish in color. Maybe from stress? I'm known to not have regular periods and miss some now and then. I'm not ually active. Any ideas? I'm too busy to go to the doctor, and don't have the money (college student). I'm going full time (cles 6 days a week- 20 credit hours and I work Sundays for a couple hours). Any ideas would be great and appreciated. Thank you.
