Second job symptoms and conditions

Hi everyone, I have just read all thirty pages of posts to try to find some answers to my crazy reaction to prednisone. My thoughts are with you all since I have had an usually severe reaction to prednisone. I was on prednisone for 1 week in October 2008 at 60 mg/day for a sinus surgery. I am still having the following side effects at full force:

Axiety to the point I can't socialize
mood swings
hot/sweating even in freezing weather
whole body shakes
severe migraines
tooth sensitivity
muscle pains
extreme thirst (I drink almost 2 gallons/day)
hungry all the time
moon face
water retention around waist
acne
hair loss
rapid heart rate
dizziness
nightmares
night sweats
high blood pressure
high hear rate

I'm not exaggerating, my parent's can contend to that. I do have a history of having sever reactions to medication and I've had all the gland and blood tests which all check out. I never had a single one of these before the prednisone - I was a healthy 22 year old.

I was wondering if any could tell me when this hell will end - my job and well-being depends on it!

I went to the doctor Friday night worried that I had pink eye. He says "No, your eyes are fine, nothing wrong there, but your cough sounds awful." so he listens to my lungs and says I have bronchitis. Yeah, I had a sinus infection a couple of weeks ago and the cough never went away. So I say, ok, what can you do? I have no insurance, the place I currently work at is cheap. He brings me 5 sample packets of Levaquin, 750 mg. Says to me "These are really good. Take one a day for the next five days. They should do the job, they are $25 a pill." I think, wow, that's some expensive medicine.
ANyway, I come home and take a pill around 8. I have a second job that I work on evenings and weekends, so I have to get up in the morning to go. I can't sleep like usual. I wake up every hour or two. First I am sweating, I get up and turn the heat down. Second time I wake up with tears running down my face, I'd been having a nightmare about one of the kids I watch dying od SIDS (How twisted is that?) Then I just keep waking up.... I go to work yesterday morning and after about 2 hours I start to get real light-headed and nauseous and my ears were burning like someone had embarrassed me to the extreme. I came home after being at work 4 hours. I felt sick to my stomach all day but thought it was because I hadn't eaten. WHen I finally ate, I couldn't stop eating. Then I did, and 2 hours later I was feeling sick again.
Not thinking anything about it being the drug, I took another one last night at 6:30. When I finally went to bed at midnight, the nightmares started all over again. I wake up crying, my body wracked with sobs, tears rolling down my face.
I don't want to keep taking this medicine if it is causing all of this but I don't have the money to go back to the doctor for something else, and I can't afford to still have bronchitis. What am I to do?
