End of My Rope

They say when you’re at the end of your rope to tie a knot and hang on. I don’t know if I can tie any more knots in my rope. I just got test results from my cardio-pulmonary test and they look “unremarkable.” The doctor suggested I have pulmonology look to see if they see something he can’t. WHAT NEXT!?! Why can’t they see anything? THREE YEARS are gone waiting for one test result after another while I’m not any better. I can’t put up with this. I want this to have a positive spin but I’m sorry that I don’t have one right now.
