Brett,
I really think it's panic/anxiety, if you've already had all of those tests.
Let me make this very clear - that doesn't mean your symptoms aren't there. Anxiety can throw us some very, very real and very, very painful/uncomfortable symptoms.
Heart racing, sweating, waking from sleep in an attack, shortness of breath - check, check and check.
I hope your therapist's appointment goes well tomorrow.
Hang in there!
