Sarah, I, too, had problems with continual anxiety. Now, I must first say that it is my husband who had his bladder removed because of bladder cancer. The anxiety was not about this.
I have a history of a couple of really rare conditions that took years to diagnose. During the times I was trying to get a diagnosis, I heard "It's all in your head" so many times from so many doctors, that I ended up with panic attacks and generalized anxiety, trying to figure out what I was doing wrong. Even after I had the diagnoses for both diseases, the anxiety continued, as did the panic attacks. The neural connections had already been formed, I guess.
I began seeing a counselor, and, although it helped some, the real help came when I found a psychiatrist who was willing to TREAT the anxiety, not try to talk me out of it. Once I went on the medication, I gradually improved. It took time, and I have been on the medication for several years. I find that I still am improving. Every once in a while, I can tell I have taken one more step. For instance, once I had a dream resolving a problem that would plague me in my dreams for years.
When I awoke, I had such a sense of relief, I couldn't believe it.
The anxiety is real, and there may be a real reason for it. I hope you can find someone who will take it seriously and help you find a treatment. It may take some time, but you will find the small steps are rewarding, and you may be able to look back next year, and say "I used to have a big problem with anxiety."
Keep us posted with your treatments.
