One UTI 3 years ago and still symptoms

July 25th 2019, went to CVS minute clinic for Uti symptoms. Dipstick indicated infection, prescribed 3 days of Macrobid. I continued to worsen and called my urologist ( Had kidney stones in the past but hadn't needed urologist since then ). She cultured the urine and it came back negative. I continued to suffer tremendously. Went to Urgent care, another urologist, my gynecologist and back to Urgent care. All cultures showed "mixed flora" and I was told I did not have an infection. No other suggestions were offered. I lost 30lbs and could not leave my house. I thought death was going to be the only escape though I was not suicidal. My primary put me on Lexapro and Ativan which helped to deal with it however I gained a lot of weight. My doc would not consider changing that medication. I'm still dealing with constant urge to urinate and sometimes pain. It ruined my mental health and marriage. Went through divorce and moving which caused a lot of stress. I asked for Pelvic PT referral. Tight pelvic floor muscles, given stretches to do. 5 sessions and discharged. That was right before Christmas. Still had symptoms. Then end of Jan had two symptom free weeks and couldn't believe it. I suddenly realized just how much this had affected my life. I felt free and normal. Then I woke up with the familiar bladder pain and it's been a struggle since. I saw a urogynecologist in Boston who said to use a suppository of Valium and Bacolfen but after 2 nights i was in the bathroom constantly ( hadn't needed to use the bathroom at night in a long time until then ). I was also told I could not use oral Ativan and the vaginal valium because they are both benzodiazepines. I could not sleep at all and it's hard to function as a teacher with no sleep. Last night I went back to Ativan and stopped the suppository. I am depressed and desperate for help. I have tried acupuncture, energy healers, Reiki and chiropractor. I have only been diagnosed with PFD not IC. Mostly it's urge to urinate, not usually pain. I have read all the message boards on Chronic UTI which I'm told is not what I have, and also Embedded infections which my doctors don't believe are possible. I'm so confused and lost. Any suggestions or direction would be life altering. Thank you.
