Um, yeah, what kind of NP says bloody urine is normal? That's not true, and I doubt mental illness could cause that. But I do understand how hard it can be to get adequate physical health care, especially if they know you have a mental illness diagnosis. I had excruciating pain and bloody stool written off for two weeks as psychosomatic until I nearly died of what turned out to be a very real autoimmune disorder. In managing my disease, I've learned that normal labs don't necessarily mean nothing's physically wrong--there are a lot of things that just don't show up in labs.

If it's at all possible, I'd advise seeing a different medical professional. It's okay to doctor shop if your concerns are being ignored and you're not being adequately treated. They can be hard to find, but there are good doctors out there who will take you seriously. (I wish I could lend you mine; he's the absolute BEST.) Don't give up just because one NP blew you off.
