First, take a deep breath,there are a mountain of reasons why you could have high protein levels in urine, one of which is stress. Ditto for blood in urine- but there is no question that you should continue on with the process of trying to find the cause. And don·t fool yourself into thinking you can go about your life as if nothing is wrong, being in denial about a possible problem will not make it go away.The not knowing, as you have found is exhausting, and the best way to stop this exhaustion is to know what the problem is and go about your life with a treatment plan in place . You sound as if your medical team are quite on the ball, and hopefully the urologist may be able to pinpoint what the reason is and how to tackle it . Good luck and please let us know how you go on with the cystoscopy.
