I Have Had A Pulmonary Work Up And A Heart

I have had a pulmonary work up and a heart stress test. Heart good and they told me "looks like there is a blockage, see you in October" when they told me about my pulmonary work up. The local dr's are not giving me any relief or answers and I'm tired of feeling so bad. It seems like I am gaining weight quickly, but I do not eat a lot. I basically need direction. I don't know where to turn when my family dr. isn't helping, or even seem to care. They are treating me like a hypochondriac.
