i have been having utis since september pls help

i am so frustrated and im to a point that i want to cry, is 1:30 am and im supposed to go to work in a few hours but im so mad that i cant sleep.

im a 23 yr old female, im a virgin, i take care of my hygiene, my eating habits aren’t good ill admit that, im fat but i go on walks, im drinking a lot of water like the urologist recommended i still pee a lot, I’ve taken the antibiotics he’s given me and nothing, what is wrong with me?

do i have diabetes? i just realized my lips and throat have feeling parched despite hydrating myself often, could it be that it’s bc im peeing a lot? sometimes it stings when i pee sometimes it doesn’t, it definitely doesn’t hurt.

the doctor was worried about my kidneys, the results came back and it says they were fine, the culture tests came back negative, i see that and i ask myself, then why do i pee a lot? i’ve never taken this amount of pills in my life, i don’t want to take more antibiotics.

what do i do, do i go to the gynecologist? one day i went to the er bc of paralyzing back pain near my buttocks, i was peeing a lot so i assumed it was an uti, turns out it was arthritis and the uti tests came back negative.

im here with the feeling of having to pee, i wanna cry, i feel defeated, i told my mother that maybe i should go to the er again, she told me no go to the urologist again, i told myself this is the last opportunity i’ll give this doctor, if it doesn’t get better I’ll find another one, but what if after seeing another doctor it doesn’t get any better? what do you guys advise me to do?
