UTI train wreck?

Hey. So. I needed to go run errands one day and because I don't have a car I ended up walking 9 miles in 90 degree weather. I drank water, juice, and even chocolate milk like crazy that day, but in the middle of the walk I felt a UTI coming on. When I got home I got a huge jug of cranberry juice and chugged it in a couple hours.

- Next morning I felt terrible

- Continued to drink water (at one point 5 lbs (90 fluid oz) in 4 hours)

- Went to the doctors

- Confirmed chronic dehydration (HOW?!), off the charts infection and blood in my urine.

- Got antibiotics

- Antibiotics did nothing.

- Got AZO

- Got different antibiotics

- One dose of AZO every 30 hours, so it is getting better....

- Went off AZO

- Felt just as bad as I did before I even went to the dr's

- Dr prescribed different antibiotics told me to go to the hospital

- Hospital said they'd get the results in 3 days

- 3 days pass and they tell me they need another sample, wont tell me whats wrong

- Can't get to the hospital for another 4 days.

- Just developed a yeast infection from the antibiotics. -_-

Are there ANY home tricks or tips for ANY of this? It's been almost a month with a terrible UTI and now a yeast infection! I am so uncomfortable! Any tips, reassuring words, tricks.... anything will be helpful. (And it's Finals week...)
