I am sorry to hear about your symptoms. Essentially, the clinician would take a thorough medial history, examine you and then determine if further investigations are needed.
This might include a chest X-ray and ECG in the first instance and further tests might include blood tests, CT scans etc
It does sound like your symptoms may be anxiety/stress related, nevertheless chest pain and difficulty breathing should not be ignored and I would certainly arrange to see a general physician, cardiologies or exercise specialist.
I hope this helps.
