Google Waterfall D-mannose - it's a really effective non-antibiotic way of treating UTI and can be used as a preventative measure/to maintain bladder health long term without side effects of risk of tolerance. It's not cheap, but it might be worth you looking into.
Your anxiety will definitely have an effect on symptoms - many of the symptoms you describe can be brought on by anxiety, so it becomes a vicious circle. Also, by the accuracy of the temperatures you're listing, and how often, I'm guessing you are actually measuring your temperature ... a lot! Don't
Unless you truly have fever symptoms (shivers, alternately hot and cold, etc), or there is some reason why your doctor has asked to check it frequently, don't take it. Your temperature fluctuates naturally, so if you keep taking it you'll notice those changes and feel your anxiety. I know it's hard not to keep picking up that thermometer, but it's really best left in the drawer!
Try to do something that stops you being able to think about how you are feeling - something that takes your mind off any symptoms you may have. Reactions to drugs are rare, especially serious reactions. Please don't think I'm trying to belittle your concerns - I'm really not - but statistically you are very unlikely to suffer any reaction to the ABs - your most likely outcome is you will feel better. So do something nice to get your mind off those niggly twinges and weird feelings and allow yourself to feel well.
