Thanks a lot for your health concerns. It seems that anxiety
and depressive symptoms are a major burden in your case, and those are difficult to assess and treat in an adequate way through an ER; your cardiologist could help but you might need to access an outpatient Psychiatrist
to adjust medications and provide further therapy and referrals if needed.
I am sorry that you have experienced frustration, hope this helps,
