pain and fear

I woke up at 1:00AM Wednesday with a blazing UTI. I kept waking up the rest of the night from the pain. I could not get a new prescription for antibiotics until I had an office visit with a doctor. I was able to get in to see the doctor on call at my OBGYN at 10:30AM that morning. Then after an hour to get my prescription filled, I returned  to work the rest of the day. I went straight to bed after work that day. By Thursday, I stayed up long enough to do some laundry before going to bed and sleeping well.
The idea of getting a UTI on a weekend, when there are no doctors around to prescribe anything, horrifies me. I know I could not possibly work my weekend job on my feet in that much pain. There are emergency clinics but even they have to send tests to labs outside and none of them have late hours. I don't know if they're open on weekends.
This infection came out of the blue. I try to drink a lot of water. I guess I'm still not drinking enough water for this to happen.
