UTI problems

Kai
This is my second UTI in two months and it wasn't as bad as my first but it's starting to get there, I'm starting to get pain in my sides and the burning is getting worse. I keep asking my parents to take me to a doctor but they refuse and I don't have my license yet because they procrastinated my permit so I can't go myself. I've been drinking almost a 100oz of water a day and I have AZO but I'm on my last pill so I don't want to take it till I'm at school but it hurts so bad. What do I do? If I go to the doctor will my insurance cover the visit or will I have to pay? I could probably get a friend to drive me but paying for it is also an issue due to my lack of a job.
