Your problems seem to fall into the just-because-your-paranoid-doesn't-mean-they're-not-out-to-get-you category.
What I'm trying to say is that it sounds like your health care people aren't taking your symptoms seriously, but that doesn't mean you don't have medical problems.
Maybe try asking around about medical professionals in your area, and let your queries focus on "Is this doctor compassionate and unhurried" rather than "has this doctor treated these symptoms."
In the mean time, drink lots of water and get adequate sleep and exercise.
And above all, "Do as I say, not as I do."
