Oh, goodness! Can you ask to be put on a cancellation list? Some doctors have a waitlist of folks who have far away appointments that they will call sooner if other patients cancel ... that might help save some time, if you can change plans in a hurry when an opening comes up. (They can do it here ... I sure hope for your sake they can do it where you are.)

I had to see one specialist once that took ages (this was before my cancer, and for a separate issue), and once I finally got to see him, we scheduled a test in hospital ... in February. Afterwards he told me he'd follow up with the results ... in July. I didn't even bother going to that appointment. I figured, whatever results he'd found weren't likely to kill me, and I was too mad to be nice. (In retrospect, that may sound very stupid, and it probably was, but in the interim another doctor figured out what my issue was, so it turned out okay at the time. But it was still a ridiculous wait time just to find out that his answer was 'We didn't see any issue'.)

Call and check! Can't hurt to ask.
