Hello and welcome to HealingWell. I understand your concerns and you certainly have a right to feel the way you do. Anytime we have a dx of something going on with our heart it causes us to feel anxious and stressed. On top of that you have a new job committment.
I am sorry you have not been able to connect with a Dr. that you are comfortable with. Please do seek out another Dr. and advocate for yourself as a year sounds like you may have what is referred to as chronic pericarditis. Please remember I am not a Dr.
